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.

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.

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.
