3.0 Safety Information

Safety precautions should be observed during all phases of operation of this instrument. The
instrument has been designed to ensure safe operation however please observe all safety
markings and instructions. Do not operate the instrument in the presence of flammable gases
or fumes or any other combustible environment. VeEX Inc. assumes no liability for the
customer's failure to comply with safety precautions and requirements.

Optical Connectors

The test platform displays a laser warning icon when the laser source is active to alert the user
about a potentially dangerous situation. Make sure that optical sources are inactive before
connecting fiber to the test set to avoid skin or eye damage, or damage to the unit. It is
recommended to:

• Deactivate the laser before connecting or disconnecting optical cables or patchcords.

• Never look directly into an optical patchcord or an optical interface (e.g. CFP, CFP2,

CFP4, QSFP+, SFP+, SFP, OTDR, LS, VFL) while the laser is enabled. Even though
optical transceivers are typically fitted with Class 1 lasers, which are considered eye
safe, optical radiation for an extended period can cause irreparable damage to the eyes.

• Never use a fiber microscope to check the optical connectors when the laser source is
active.

Electrical Connectors

Telephone lines may carry dangerous voltages. Always connect the electrical test ports to
known test interfaces which carry low level signals.

OTDR Series e-Manual, D07-00-076P-RevC00 Page 10 of 107

4.0 Theory of Operation

4.1 OTDR

The principle of OTDR operation is based on measuring the Rayleigh back scattering signal
when a single powerful optical pulse passes through an optical fiber. The weak back scattering
signal is registered by an optical receiver, converted into digital form and averaged many
times.

The OTDR calculate distance with next formula:

Distance = c * t / (2 * n)

where c – light speed in vacuum, n – optical fiber index of refraction, t – time
delay between pulse emit and it
registration by receiver

Each sample converted by ADC into digital form is registered in the RAM. To measure the
back-scattering signal precisely, repeated triggering optical pulses is performed. The processor
averages samples, corresponding to the same points of the optical fiber that leads to the
increasing signal-noise ratio. After several cycles, the obtained signal values are transferred
from RAM and displayed. Then, the process of measuring, averaging, and cleaning RAM
registers is repeated again.

OTDR – Principle of Operation

OTDR Series e-Manual, D07-00-076P-RevC00 Page 11 of 107

4.2 Light Source

An optional light source is available and designed for generating continuous optical radiation.
The light source output is the same as the OTDR port and uses the same laser diodes and
optical splitter. The radiation power is stabilized with the help of external photodiode and power
stabilization circuit.

The light source has two operation modes: Continuous and Modulated/tone (270, 1000 and
2000Hz).

The average power at modulation mode is 2 times lower (3dB) than in continuous mode of
operation.

4.3 Optical Power Meter

The OPM is equipped with an InGaAs photodiode (1mm diameter) to measure optical power.
For standard power PM1 measurement range (+10dBm), radiation falls directly on the
photodiode. The OPM will support both MM and SM fiber with the APC or UPC connector type.

For extended measurement PM2 range (+25dBm), an integrating sphere with a photodiode is
used. Input power is attenuated by the integrating sphere by approximately 100 times.

The current of the photodiode is amplified and converted into digital form with the help of
analog-digital converter. The received digital signal is processed by microprocessor and the
value of the measured optical power is displayed.

4.4 Visual Fault Locator

The unit is equipped with an optional Visual Light Locator (VFL) to visually identify breaks in
the fiber typically hidden in the OTDR dead zone.

• Output power: 0 dBm (Typical)

• Operation modes: Continuous wave (CW) or 2Hz modulation

OTDR Series e-Manual, D07-00-076P-RevC00 Page 12 of 107

5.0 Basic Operation

5.1 Test Ports and Interfaces

OTDR testing: The optical fiber under test is connected to either the OTDR or OTDR Aux

(Filtered SM or MM) port on the top panel. The type of the optical fiber connector must
correspond to the OTDR connector or adaptor type, including the connector polish.

Optical Power Meter (OPM) testing: The optical fiber is connected to the OPM port on the
top panel. Depending on fiber connector type, use interchangeable adaptors. FC, SC, ST or
LC type are supplied standard.

Visual Fault Locator ((VFL) testing: The optical fiber is connected to the VFL port on the top
panel. The VFL interface is fitted with universal 2.5mm sleeve accepting all 2.5 mm connector
ferrules.

Note:

Optical Connections - The optical fiber connector must be cleaned prior to connecting to the

fiber under test. Dust and dirt severely impacts optical performance.

Refer to Fiber handling procedures for cleaning tips and information.

6.0 Test Fiber and Initial Preparation Introduction

Dirt, dust, and other contaminants severely impact high-speed data transmission in optical
fibers and dirty connector end-faces are often the #1 cause of link failures. High insertion loss
and/or high back reflection can result in transmission loss or high bit errors and poor BER.

Furthermore, most measurement variations and test repeatability conditions in fiber-optic
systems can be traced back to the cleanliness of optical connections. Contamination of fiber
end faces not only affects optical power levels but also impacts back reflectance performance
and levels which is harmful to sensitive optical components.



OTDR Series e-Manual, D07-00-076P-RevC00 Page 29 of 107

6.1 Contamination

Optical connectors are susceptible to contamination from air borne particles and human body
oils when exposed. Left over liquid residue from improper cleaning can also leave the fiber end
face contaminated. The smaller the fiber core, the more severe the problem is likely to be,
especially when you consider that fiber core diameters can range from 62.5 microns all the
way down to 8 microns in size. Below are some examples viewed by a 400x Fiber microscope:

6.2 Inspection

Whenever possible, inspect the fiber-optic connection (connectors, bulkheads, and test
interfaces) with a fiber microscope. It is recommended to wear laser safety glasses when you
work with fiber-optic connections, and always check that you disconnect the laser or
transmitter before you begin cleaning the connector end faces.

OTDR Series e-Manual, D07-00-076P-RevC00 Page 30 of 107

6.3 Cleaning Procedure

To ensure proper and effective cleaning of optical fiber connectors and interfaces, please
equip yourself with the following cleaning materials:

• Isopropyl alcohol

• Lint free soft tissues

• Ferrule cleaners (1.25mm and 2.5mm versions)

• Connector reel cleaners (CleTop or similar)

Procedure

1. Dab the contaminated connector end-face with a wipe that has been dampened with
Isopropyl alcohol - the solvent will dissolve and remove contaminants that have dried and
attached to the connector or fiber end-face.

2. Rub the fiber end-face perpendicularly against a dry lint free wipe several times.

3. Alternatively, use compressed air to dry the surface quickly. Do not blow or allow the
connector end face to air dry as this may leave a residue behind which is often more
difficult to clean and which can attract even more dirt.

4. Re-inspect the fiber end-face with an optical microscope to check that all the contaminants
have been removed properly - if not, please repeat the process.

Note:

Using Compressed Air - In some clean air situations, you can use filtered air, which is free of

oil and moisture to remove debris and clean a fiber optic connection. However, unless you
follow very strict cleaning procedures, air-driven contaminants can cause more problems.

If you need to use compressed air, hold the can upright. If the can is held at a slant, propellant
could escape and dirty your optical device. First spray into the air, as the initial stream of
compressed air could contain some condensation or propellant. Such condensation leaves
behind a filmy deposit.



OTDR Series e-Manual, D07-00-076P-RevC00 Page 31 of 107

6.4 Best Practices

• Never touch the end face of an optical fiber connector with your hands or fingers.

• Always install dust caps on unplugged fiber connectors.

• Store unused dust caps in a re-sealable plastic bag to prevent dust accumulating.

• Never re-use optic cleaning swabs or lint free wipes. Always discard materials that have

been used.

• Ensure all alcohol or solvent residues are removed after using wet cleaning techniques

• It is recommended to re-inspect the bulkhead receptacles and connector end face using

a fiber microscope following the cleaning and prior to use.

• The flow diagram below describes a best practice prior to connecting your optical fiber.

6.5 Connectors

6.5.1 Connector Types

In fiber optic networks, you will come into contact with many different connector types, the
most common being described below:

ST Connector

ST stands for Straight Tip-a quick release bayonet style connector developed by AT&T. STs
were predominant in the late 80s and early 90s and are still one of the most commonly used
fiber optic connectors in networking applications. They are cylindrical with twist lock coupling,

2.5mm keyed ferrule.

ST connectors are used both short distance applications and long line systems. The ST
connector has a bayonet mount and a long cylindrical ferrule to hold the fiber.

FC Connector

FC stands for Fixed Connection - it is fixed by way of a threaded barrel housing. FC
connectors are typical in test and measurement environments and for single- mode
applications.

FC is the fiber optic connector standard for Nippon Telephone & Telegraph (NTT) installations,
developed with Nippon Electric Co. (NEC).

Note: The FC screws on firmly, but make sure you have the key aligned in the slot properly
before tightening.



OTDR Series e-Manual, D07-00-076P-RevC00 Page 33 of 107

LC Connector

LC stands for Lucent Connector. It is a small form-factor fiber optic connector that uses a 1.25
mm ferrule, which is half the size of the ST / SC connectors.

It uses a standard ceramic ferrule connector. The LC has good performance and is highly
favored for both multimode and single mode applications, especially in high-density connector
facilities. The LC connector is available in simplex or duplex cables.

SC Connector

SC officially stands for Subscriber Connector; however, some people believe that “Square
Connector,” is the correct name. It is a general purpose push/pull style connector. It was
developed by NTT, which has an advantage in LAN/enterprise networks where duplex cabling
to support TX/RX channels are commonly used.

SC Connectors are frequently used network applications. The connector is square and keyed
with push-pull mating, 2.5mm ferrule, and molded housing for protection. The SC is a snap-in
connector that is widely used in singlemode systems due in part for its performance. The snap­in connector latches with a simple push-pull motion.



OTDR Series e-Manual, D07-00-076P-RevC00 Page 34 of 107

E2000 Connector

Developed by Diamond, this connector has proven its performance worldwide in CATV and
telecommunication networks. The connector features a spring-loaded shutter used to protect
the ferrule from dust and scratches, and to provide increased safety protection. It uses a high
precision Zirconia full ceramic ferrule with an insertion loss of 0.1dB. The APC version has a
return loss of better than 85dB. The connector is especially suited for installation in global high
performance networks.

The E2000 patchcords is available in simplex and duplex versions and comply with IEC 61
754-15 and TIA/EIA 604-16 standards

6.5.2 Connector Performance and Polishing

Polishing of fiber optic connectors is the process of polishing the end-face of the ceramic
ferrule within the fiber optic connector. The purpose is to improve the light transfer between the
mating of connectors, in order to minimize optical losses and reducing reflections. This is an
important aspect of fiber optic communications as losses affect the quality of the light signals.

There are two main types of losses that are affected by the style and quality of polishing, which
dictate the optical performance level of terminated fiber optic connectors:

• Insertion Loss (IL) - The most important performance indicator of a fiber optic

connection. This is the loss of light signal, measured in decibels (dB), during the
insertion of a fiber optic connector.

• Return Loss (RL) - Also known as back reflection, is the portion of the light signal that

is reflected back to the original light source. This occurs as the light is reflected off the
connector and travels back along the fiber to the light source. This indicator is measured
in negative decibels (dB). When reading return loss figures, the higher the absolute
value of the decibel unit means the better the performance of the interconnection.

The amount of insertion loss is affected by fiber alignment, and/or the quality of the finishing on
the end of ferrule, while reflectance is affected by the style of polishing on the ceramic ferrule
in a connector. There are three different styles of polishing, reflected by their shape of the
finish:

• Physical Contact (PC) - In the PC style finish, the fiber is polished to a smooth curve.

As the name implies (i.e. physical contact), the ferrules of adjoining fibers come into
physical contact and this reduces the air gap between the contacting ferrules, resulting
in lower insertion losses. The smooth curve in the PC style is designed to reduce the
return loss by reflecting the light out of the fiber. However, the PC polishing style incurs
more return loss than other styles.

OTDR Series e-Manual, D07-00-076P-RevC00 Page 35 of 107

• Ultra Physical Contact (UPC) - The UPC style ferrule has the shape of the PC style,

except they are polished with several grades of polishing film that allows for an ultra­smooth surface. The main difference between UPC and PC is that the former have
lower return loss.

• Angled Physical Contact (APC) - The APC style produces the lowest return loss when

compared to other styles. The ferrule is polished to an angle of 8 degrees. The angle is
calculated so that it is less than the critical angle, which ensures light is not propagated
back along the fiber.

Connector Polish and Performance

Typical Return loss values are:

Polished Connector ~ -45dB

Ultra-Polished Connector ~ -55dB

Angled Polished Connector up to ~ -65dB

benefits. In OTDR applications, you will regularly come across the following types:

Bare Fiber

• Usually Spooled in 25km spools

• 250 to 400um acolyte buffer / polyimide

• PM Light Sensitive Bare

• Fiber Adaptor is a useful accessory and provides quick connection to check fiber

• Outer Jacket can be of a variety of materials

• Usually longer runs and can be terminated with almost any style of connector

Ribbon

• Commonly used in LAN and PON applications with MTP/MPO connectors

6.6.2 Fiber Patchcord

A fiber patch cord is a piece of fiber cable that is used to connect the OTDR to the fiber under
test. In a typical installation, fibers comprising the incoming cable will be “broken out” and
terminated in a patch panel or wiring closet. One end of the patch cord is usually connected to
the OTDR while the other end is progressively moved along the patch panel as measurements
are made on each fiber.

The patchcord plays a critical role in fiber measurements and users should ensure that a high
quality patchcord is always used, because this can and will have profound performance on test
results and traces.

Factors affecting the choice of patchcord include:

• Fiber type – singlemode, multimode or ribbon

• Connector type (ST, SC, FC, LC, E2000, MTP/MPO, etc.)

• Dead-zone requirements (Refer to Section 4.2) Back reflection performance

• Insertion Loss

• Durability and Longevity

• Bend Limitation

6.7 Inserting the Fiber

Carefully align the optical fiber connector to the port to avoid rubbing the fiber against the
external part of the port or any other surface. If the interface of the connector has an alignment
key, make sure to insert it correctly into the corresponding groove.

Push the connector in and make sure the optical cables are inserted to guarantee sufficient
contact. If the connector has screw bushing, screw down the connector to fix in the optical
fiber. Do not over-screw the connector or it will damage the optical fiber and the port.

6.7.1 Preventing Inaccurate Readings

To achieve maximum power and prevent false readings, clean the optical fiber connector
interfaces before inserting them into the test port.

Please ensure the correct fiber connector type is used before inserting it into the test port or
connector. Mismatched connector types will damage the optical end faces and the test set.

Note: If the optical fiber is not aligned properly and/or completely connected, it will
cause serious loss and reflection.

6.9 Visual Fault Locator (VFL)

The unit is equipped with an optionally built-in Visual Fault Locator (VFL) to trace and visually
identify breaks in ODFs, bare fibers (900 µm), and patch cords that are typically hidden in the
OTDR dead zone.

The VFL works by injecting a 650nm visual red light into the fiber (up to 5 kilometers/3 miles)
to bend a single fiber strand and force light to exit the center of the fiber. It traces it to identify
faults through light leakage. It identifies fiber strands, connectors, breaks, bends and other
potential problems or anomalies on events.

To see the most recent VFL specifications, go www.veexinc.com.

PROTECT YOUR EYES!

Never look directly into the VFL’s light. It is a Class II laser and emits
laser radiation that will harm your eyes.

Use the Home icon (FX150/FX300) or App key (FX300) to toggle between active test
applications (OTDR, OPM, VFL).

For patchcords with dark cabling or any outdoor cable or bend-insensitive
patchcords (armored cables), VFL will not work because there is no way
to bend fibers.

6.10 Optical Light Source (OLS)

The unit can be equipped with an optional Optical Light Source (OLS) to use in conjunction
with the OPM and test the entire fiber infrastructure. It identifies microbends, bad
splices/connectors, and fiber breaks through visible laser light leakage. Use the automated
feature to control both units at each end and test the fiber (multimode or singlemode) at
different wavelengths. The OLS radiates continuously or in pulses.

measured.

• Test Mode: Select between Power or Loss measurements.

• Power Meter (OPM): In Power Meter mode, the test set presents the direct power

readings, which are displayed in dBm, mW or uW units. You can perform unit
conversions by using the dBm, mW or uW buttons.

• Loss Meter: In Loss Meter mode, the test set reports the difference in power
readings between the Laser Source (LS) output being used and what is currently
present at the connector after being attenuated by the fiber. The results are
presented in dB.

Loss meter must be referenced (calibrated) to the Laser Source output.

OTDR Series e-Manual, D07-00-076P-RevC00 Page 61 of 107

To calibrate the Loss meter to the LS:

1. Connect the LS the OPM using a short patch cord.

2. Tap the Reference button to record the 0dB point. A reference point is established and the
calibrated LS can be connected to the far-end of the fiber to measure the loss.

• Hold: Freezes the last power or loss reading on the screen. Hold appears on the white

screen when tapped. Tap Hold again to unfreeze it.

• Save: Records instantaneous power or loss readings in the Results tab. The Save

button must be used to record these individual readings (e.g. same cable at different
wavelength). Use the Folder button to save the complete set of results.

Saving the power or loss readings is useful when measuring multiple
fibers or testing one fiber with multiple wavelengths.

• Reference (Reference Power Level for Loss Meter Test Mode): Sets the output

reference level to measure against when a short and clean optical patch cord for the LS
is connected directly to the unit’s OPM port.

Press Set to store the reading or press Cancel to keep the previously stored value.

6.11.1.2 Setting Pass/Fail Limits

Whether measuring optical power or loss, there are always power input limits (saturation and
loss) or attenuation allowances that determine whether the fiber cable meets the requirements
for the desired application or network elements.

• Power Limits: Select the Power Limits (dBm) checkbox and enter the Minimum and

Maximum power levels allowed for the application (e.g. in line with the transceiver’s

dynamic range). If the power reading falls beyond those limits, the power measurement
reading will turn red.

• Loss Limits: Select the Loss Limits checkbox and enter the Minimum and Maximum

amounts of optical power loss that are acceptable for the application or specified for the
cable or installation. You can specify the total amount of attenuation in dB, or select the
dB/km or dB/mi if the results are being compared against cable specifications. If
needed, enter the Length of the cable under test for the test set to make the
conversion.

7.0 Working with the OTDR

7.1 Test Setup

Note: Screens provided in this section are based on the V300 series OTDR. Slight differences
may occur between FX150, FX300, MTTplus, or RxT platform screens when describing OTDR
and OPM operation.

7.1.1 Initial Settings

Wavelength: Select the wavelengths, which you wish to use to test the fiber.

• OTDR - If the OTDR contains both single and multi-mode optical fiber test ports,

selecting a single-mode OTDR wavelength (SM1310, SM1550, SM1625) automatically
prevent the selection of multimode OTDR wavelengths (MM 850, MM1300) and vice
versa.

• OTDR Aux - The Aux port is reserved for:

• In-service filtered testing at 1625nm or 1650nm.

• Multimode testing when OTDR is equipped with both singlemode and multimode

capability

For RxT-4111 only

• DWDM Grid - Select the channel that you wish to test

• Frequency – The displayed frequency automatically matches the chosen test

wavelength/Channel

• Wavelength - Select the test channel/wavelength

Fiber/Connector Check: (Can only be deactivated in Manual mode)

• Fiber Check - Confirms if a live fiber carrying customer traffic is connected to the OTDR

if a live fiber is detected, a warning is displayed, and the OTDR laser will not transmit
thus preventing any service disruption.

• Connector Check - When selected, the unit will check the loss and reflectance of the

OTDR connection to the Fiber-Under-Test or launch fiber. If excessive loss or poor
reflectance is detected, the OTDR displays a “Bad connection detected” message. If a
patchcord is too short, the user may also get this message. The User has the option to
stop the test and check the fiber or resume the measurement.

OTDR Setup (Page 1):

Test Parameters (all OTDR models)

• Mode: Manual, Auto, VScout, or VScout Profiles (optional)

• PON Type: Not A PON, Manual PON or Auto PON

• 1st Splitter (manual mode)

• 2nd Splitter

• Distance range (km, m, miles, kilofeet): maximum value of measured distances; the

value of distance range should exceed the expected length of the fiber under test (20%
more). The distance unit type can be set in page 2 of Test Setup.

• Pulse Width, ns: the value of the optical pulse duration; the range of acceptable optical

pulse values depend on the selected distance range and is automatically set by the
OTDR software. Short pulse widths provide better resolution and produce the best
event and attenuation dead zones. Short pulse widths however inject less optical
energy into the Fiber-Under-Test (FUT), resulting in a noisier trace and lower dynamic
range. Longer pulse widths provide the highest dynamic range and are used to test long
fibers.

• Resolution, m: distance between two samples (sampling interval) of the trace; values

depend on the selected distance range. Select smallest value to measure events
spaced close together and use largest value to for longer ranges. Auto mode will deter­mine best value for Fiber Under Test

• Measurement time, min:sec: determines the duration of measurement process with

averaging. Use Live mode to perform monitoring of the fiber in Real Time. Longer
averaging time improves the SNR and produces a “smoother” trace.

• Optimized For: Select Test Mode: Automatic DR/DZ, maximize dynamic range (DR

mode) or best deadzone, sacrifice range (DZ mode)

Fiber Properties

• Fiber Model: Select type of fiber to be tested to auto populate Index of Refraction (IoR)

and Backscatter co-efficient (BS) values.

• Wavelength (nm): Select desired wavelength for fiber properties.

• Refractive index N: Setting for each available wavelength (also known as group index)

is used to convert time to distance. Setting proper value (1.2000-1.8000) determines
accurate distance measurement. IoR provided by the cable of fiber manufacturer.

Refractive index can be changed for any stored trace. Enter a custom value or select
fiber type to populate corresponding values.

• Backscattering coefficient, BC: represents level of backscattering in a particular fiber.

It is used for Reflectance and ORL measurement and can be obtained from the fiber
manufacturer. Backscattering coefficient can be changed for any stored trace.

Other Parameters

• Auto Zoom Trace: Use this mode to auto scale the viewing window at the end of the

test.

Note: Disable this feature when using Realtime test mode.

The Fiber/Connection Check is set to ON by default. Tap the checkbox to disable.

• Fiber Check: alerts that live traffic detected and disables OTDR laser to prevent service

disruption.

• Connector Check: checks the loss and reflectance of the OTDR’s connection to the

Fiber-Under-Test or launch fiber. Excessive loss (>1.5dB) or poor reflectance (<-35) will
result in a “Bad connection detected” message. User can stop the test and check the
fiber or resume the measurement.

For OTDR with built-in internal launch fiber, (G.657), the OTDR connector insertion loss
will depend on the fiber type connected to the test set. Mismatched fibers can result in
higher panel loss than expected connector loss. Use the Span button to enter fiber
mismatch compensation. Mismatch fibers should not impact Reflectance.

Span Settings

Press the Span button to configure Span settings.

• Span begin: Used to identify where a launch cable ends and test fiber begins. Defines

the start of analysis by distance or event index. This will appear as a large green arrow
pointing right on screen.
If Event #1 is the end of the launch fiber, set the Span Begin Index to “1”.

• Span end: Defines the end of analysis by distance or event index and mark the end of

the test fiber. This will appear as a large green arrow pointing left on screen.
If a launch fiber is used at the far end of the test fiber, set the Span End Index to the
Event # associated to the location where the far end launch fiber starts.

• Include Event Loss: Check if you don’t want to include connector loss in Total loss

summary.

• Compensated Loss (dB): For OTDR with built-in internal launch fiber, (G.657), the

OTDR connector insertion loss will depend on the fiber type connected to the test set.
Mismatched fibers can result in higher panel loss than expected connector loss. Use the
Span button to enter fiber mismatch compensation. Mismatch fibers should not impact
Reflectance.

7.1.3 Auto mode

To set OTDR test parameters automatically, select Auto Mode under Test Parameters. In this
mode, the OTDR performs a short measurement and analysis of the fiber and automatically
determines optimal test settings. This process typically takes less than 5 seconds.

Auto mode is intended for inexperienced operators and only uses single pulse/wavelength.
However, the user must still specify if they are testing point-point or a point-to-multi-point
network which are typical of PON and RFoG networks. In Auto mode, the user can only set the
test wavelength/s. Distance Range, Pulse Width, Resolution and Measurement time are set
automatically by the unit.

• Test Wavelength/s

• (singlemode, multimode, singlemode live or filtered (1625 nm or 1650 nm))

• PON Type

• Not a PON (point-to-point)

• Manual PON - 1st Splitter and 2nd Splitter (1x2, 1x4, 1x8, 1x16, 2x2, 2x4, 2x8, or

7.2.1 Analysis Thresholds

OTDR Setup (Page 2):

Events that exceed the Analysis Threshold settings are reported in the Event table - these
parameters include:

• Splice Loss (dB) - The setting range for this parameter is 0.01 dB to 9.99 dB in 0.01 dB

increments. The default value is 0.020dB.

• Reflectance (dB) - Defines the lowest Reflectance value that will be reported by the

analysis. The setting range for this parameter is -70.0 dB to -20.0 dB in 0.1 dB
increments. The default value is-65.0dB.

• Fiber End (dB) - Defines the value which will be reported in the Events analysis. The

setting range for this parameter is 1 dB to 99 dB in 1 dB increments. The default value
is set to 20dB but for non-PON spans, a 3dB value is recommended.

• Macrobend (dB) - Defines the detection value with a default value 0.200dB.

A non-reflective event will be reported as a macrobend if its loss at a longer wavelength
exceeds its loss at a shorter wavelength. Macrobend detection requires at least two
singlemode wavelengths being tested - 1310 nm and another either at 1550 nm or 1625
nm. The range for this parameter is 0.3 dB to 2 dB in 0.1 dB increments. The default
value is 0.2dB

7.5 Measure Mode

There are several methods available to manually measure fiber characteristics. Prior to
performing manual measurements, it is important you become familiar with the Markers and
Zooming capabilities of the unit.

7.5.1 Markers Controls

7.5.1.1 Marker Operation

Markers are provided to measure distances accurately. Depending on measurement mode and
viewing window, one or more markers are at the User’s disposal. The Markers can be moved
using the touchscreen or using the left/right buttons on the rubber keypad (not available on
MTTplus or FX150).

The Markers display the following:

• Distance from the start of the trace to Marker “A”

• Distance from the start of the trace to Marker “B”

• Distance in between Marker “A” and Marker “B”

Note: As you move the Markers, the distance information updates automatically.

The active Marker is depicted by two small arrows pointing inwards at the base of the Marker

The Marker is divided into a thick (bottom) and thin (top) line. To move Marker A or Marker B
individually, select and drag the Marker on the thin portion of the marker. To move both
Markers together, select and drag any Marker on the thick portion of the line.

If the Markers appear off screen, use the Markers button on the right side bar to bring and
display the Markers on screen.

If a marker is moved too close to another, both will move together to ensure minimal distance
between them.

The markers can be moved separately as well as in pair (or 5 markers simultaneously in the
LSA attenuation measuring mode).

OTDR Series e-Manual, D07-00-076P-RevC00 Page 85 of 107



At the top part of the screen next to the markers, the position of the marker with respect to the
beginning of the optical fiber is indicated in kilometers, miles or feet.

In the data line at the bottom of the screen you will see the parameters of the trace
corresponding to the markers’ position and measurement mode.

7.5.1.2 Zoom/Scroll Controls

Zooming operations are possible in both Events and Measure mode.

• Zoom/Scroll icon - Toggle between and enables Zoom/Scroll mode.

• Zoom mode - Magnifying glass icon appears on screen. Draw a rectangular box

over the trace with the stylus to create a zoom area. Visible part of the trace in
Preview window is marked with dotted rectangle.

• Scroll mode - Trace can only be scrolled after zooming. Hand icon appears on
screen.

User is now able to drag the trace in any direction. The mode resets to Zoom
immediately after one scroll operation has been completed.

• Zoom Out - Resets display area completely.

• Zoom Lock - Locks horizontal and vertical controls so zoom aspect is kept uniform.

7.5.2 Distance Measurements

DDiissttaanncceemmeeaassuurreemmeenntt––mmeeaassuurreeeexxppaannddeeddttrraacceevviieewwmmooddee

When a trace is displayed as show above, the fiber length is automatically measured from the
start of the trace (or Span Begin) to each of the two markers and in between the markers.
Proper marker placement is critical for accurate measurements. To position the marker/s
accurately, expand the trace horizontally and vertically (using the Zoom Controls) and position
the marker on event’s left edge (first rising or falling pixel).

The distance (km, miles or feet) will be indicated next to the top of the marker.

Note: The distance accuracy depends on the correctness of optical fiber refraction index value
setting.

7.5.3 Loss Measurements

Loss Modes - Several Loss modes are available for manual measurements depending on

measurement application:

• 2-Pt Loss

• 2-Pt LSA

Two Point Loss measurement

• Reflectance

• ORL (Optical Return Loss)

• Splice Loss

7.5.3.1 Two Point Loss (2-Pt Loss)

The 2-Point Loss mode uses a data point at Marker A and Marker B to calculate the dB level
difference between the two points. Usually the backscatter level value of Marker A is greater
than the level of Marker B and a positive loss measurement is displayed. If the loss value is
reported as a negative quantity, it is termed a “gainer.” Measure loss between two points using
the Loss (2-point) mode (using two markers):

OTDR Series e-Manual, D07-00-076P-RevC00 Page 87 of 107



• The data at the bottom of the screen displays: Distance between markers A-B

• Loss between markers A-B in dB

• Attenuation between markers A-B

7.5.3.2 Two Point LSA (2-Pt LSA)

To increase the accuracy of a loss or attenuation measurement, a section of the trace
preceding and following the marker A and marker B can be approximated by a straight line. In
this mode, a Least Squares Approximation technique is used to determine the best intercept
values based on the marker positions. The length of these LSA sections is user selectable.

• Select LSA from drop-down list - An approximation line will appear on the screen
between markers. The data box at the bottom displays:

• Distance between marker A and B (km, miles, feet)

• Level difference in dB

• Attenuation based loss/distance

7.5.4 Splice Loss Measurement

Determines the Splice Loss in the optical fiber connection using the five markers method.

SSpplliicceeLLoossssuussiinngg55--PPooiinnttLLSSAAmmeetthhoodd

1. Select trace for measurement (if multiple traces are displayed on screen). The trace to be
measured can be selected using the green arrow in the trace overview window.

2. Select Splice (Spl) from drop-down list.

3. Expand or zoom the trace horizontally and vertically (using Zoom Controls) and position
event in the middle of the screen using the scroll function. Always ensure that a part of the
trace is visible on either side of the event so you can place markers properly.

4. Position center marker on the event’s rising or falling edge. You can use the rubber keypad
to place the marker exactly, if needed.

OTDR Series e-Manual, D07-00-076P-RevC00 Page 88 of 107

5. Position the first two markers on a section of backscatter preceding the event and position
the last two markers on a section of backscatter after the event ensuring that enough
pre/post backscatter is used to make an accurate measurement. Markers A and B should
be placed on the left and right but as close to one another as possible. The whole transition
section should stay between them.

Note: All five markers can be moved independently or moved as a group simultaneously
depending which marker is active.

The sections between the first two markers and the last two markers are approximated by
straight lines (LSA) whilst the value of event loss is defined by the position of the center
marker.

The result box at the bottom of the screen displays:

• Spl (km, meters, miles or feet) - distance of center marker

• Loss of the event in dB based on the pre/post LSA sections and center marker

• Reflectance in dB if event is reflective

7.5.5 Reflectance Measurement

Reflectance is measured in -dB (negative decibels). A smaller negative value (-65dB) indicates
a smaller reflection whereas a larger negative value (-45dB) indicates a larger reflection.
Larger reflectance will appear as a higher spike on the trace.

1. Select trace for measurement (if multiple traces are displayed on screen). The trace to be
measured can be selected using the green arrow in the trace overview window.

2. Select Reflectance (Refl) from the drop-down list at the bottom of the display.

3. Expand the trace horizontally and vertically (using Zoom Controls) to display the reflection
correctly. The entire reflection should be displayed including a small section of the trace
preceding and following the event.

4. Place the left marker on the event’s rising edge. The right marker is placed on the peak of
the reflection.

The result box at the bottom of the screen displays:

• Distance of A cursor (reflection) from Start of test fiber

• Distance of B cursor (top of reflection) from Start of test fiber

• Distance between markers A->B

• Reflection for this even (-dB)

7.5.6 ORL Measurement

ORL is the total amount of light being reflected back towards the transmitter or source. This
includes all backscatter and all reflections. The OTDR can calculate ORL from the fiber trace
using the following procedure:

1. Make sure the Trace is active.

2. Select ORL from drop-down list.

3. Place the marker A at the beginning of the fiber and marker B at the end of the fiber span
under measurement.

The Result box at the bottom of the screen displays:

• Distance to A cursor

• Distance to B cursor

• Distance between markers A-B

• Loss between the markers A-B (dB)

• Optical Return loss (ORL), dB

7.6 Traces

Select the Traces tab to view the active or measured OTDR traces. The color-coded blocks
represent the corresponding trace viewed in the OTDR display.

The OTDR can display up to ten traces simultaneously i.e. an active trace and nine additional
traces.

To view the trace, select the necessary file using the check box. The trace will be activated
automatically and displayed on screen. Traces are displayed along with the following
parameters;

• Name - File name as saved

• Dir – AB or BA

7.6.1 Trace Properties

The traces in the memory are saved in BELLCORE, version 2.0 format. The OTDR trace files
have the extension .sor which means Standard OTDR Record.

These OTDR trace files can be opened by the software of other OTDR vendor applications
provided the format is supported.

If the measurement was performed at several wavelengths simultaneously, the traces are
saved as a group i.e. they will share the same common name but with wavelength added (e.g.
01_meas_1310 and 01_meas_1550, etc.)

Press the Information button in the right sidebar to open the Trace Information window. The
window contains following information relating to the saved file:

• Device: OTDR supplier name, Mainframe ID and serial #, and optical module serial # (if

applicable)

Span Begin and Span End

Refer to section Launch/Receive fiber offset.

The user can offset the length of an external launch fiber or patchcord, which is connected to
the fiber under test; otherwise, it becomes part of the fiber span and analysis. The launch fiber
can be offset or compensated in any of the following ways:

• Entering the known distance manually in km, meters, miles or feet.

• Entering the index # based on the event table.

• Positioning the left marker at the event and pressing Span start in the right side column.

7.6.2 Saving OTDR Traces

The same procedure applies to offsetting Receiver fibers which are often used in Fiber to The
Antenna (FTTA) applications.

Note: The FX300 and RXT OTDRs have a built-in launch fiber which is 40 meters in length.
This fiber section will appear in grey color preceding the first event. This internal launch fiber
allows the user to characterize the first connector of the fiber under test and evaluate its
performance (insertion loss and reflectance). The MTTplus OTDR has an optional built-in
launch fiber.

Using any of the above methods, the launch fiber can be offset and excluded from the fiber
span measurement.
