1 Introducing the FTB-5700
Single-Ended Dispersion
Analyzer
The FTB-5700 Single-Ended Dispersion Analyzer is the world’s first
combined CD and PMD analyzer doing both measurements from a single
end of the fiber. It features a single connector port and software for both
type of measurements; CD and PMD are characterized by pressing a single
button. This is done without the need for a remote unit or light source.
As long as the remote end of the fiber is unterminated and with a UPC
connector, a single technician can perform advanced testing, that is, CD
and PMD measurements. The results are also compiled into a single test
file and a single report for both tests.
Typical Applications
With its dynamic range, level of accuracy and feature set, the FTB-5700
Single-Ended Dispersion Analyzer is a perfect tool for any network
manager or technician to perform advance testing of 10 Gbit/s networks or
faster, on any fiber length up to 120 km. The FTB-5700 Single-Ended
Dispersion Analyzer helps validating fiber quality for the given speed or
providing information enabling compensation.
Single-Ended Dispersion Analyzer 1
Introducing the FTB-5700 Single-Ended Dispersion Analyzer
Basic FTB-5700 Single-Ended Dispersion Analyzer Operation
Basic FTB-5700 Single-Ended Dispersion
Analyzer Operation
The purpose of the FTB-5700 Single-Ended Dispersion Analyzer unit is to be
simple of use, with minimal parameter setting requirements. The
parameter most likely to be changed by a user is the fiber type.
In order to achieve optimal measurements, you must however remember
a few concepts:
³ The measurement technique for the unit requires only a strong
reflective event at the end of the link to perform CD and PMD
measurements. The measurement is taken at the location of this
reflective event at a wavelength of 1550 nm.
Note: Reflective events are caused by an abrupt discontinuity in the index of
refraction. They cause a significant portion of the energy initially launched
into the fiber to be reflected back toward the source.
³ You must have a UPC connector at the end of the fiber to measure the
overall link. If the appropriate termination is not found, the unit returns
an error message (see Troubleshooting on page 65 for details).
Note: Other reflective terminations include mirror connectors, fiber pigtailed
mirrors, cleaved fibers. However, do not use fiber loop mirrors or
Faraday-type mirrors.
2 FTB-5700
Introducing the FTB-5700 Single-Ended Dispersion Analyzer
Basic FTB-5700 Single-Ended Dispersion Analyzer Operation
Once the fiber end event position is found, the unit checks the dynamics
and evaluates the wavelength range over which to perform the
measurement. It then selects the acquisition conditions and sequence of
the measurement before starting the acquisition itself.
You must also remember that the fiber under test (FUT) must meet the
following requirements for optimal testing conditions:
³ The FUT length must be terminated by a UPC connector.
³ The FUT length must be less than 120 km.
³ The FUT must not have a filter at 1550 nm.
Note: Since the instrument is single ended, it cannot measure through
components that allow light to travel only in one direction, such as
amplifiers and circulators.

Setting PMD and CD Acquisition Parameters
Parameter Details
PMD Fiber type Must be set to one of the following types:
³ Telecommunication: also known as strong coupling.
If you are working directly in the field, you will always
use this fiber type.
³ Polarization-Maintaining (PM): also known as weak
coupling. This type is rarely used and is required for
specific types of tests only.
Note: Traces taken with a particular fiber type
cannot be reanalyzed with a different fiber
type afterwards.
Analysis Range The analysis range is the value used to calculate the ITU
grid and the maximum value for the acquisition. The
analysis range can be different from the wavelength
measurement range.
Fiber with
aerial sections
If the fiber installations are, for example, between
buildings, or suspended to reach the intended location,
the movement created by wind or other outside elements
can affect the PMD measurement. Select this option to
compensate for such possible movements.

Cleaning and Connecting Optical Fibers
IMPORTANT
To ensure maximum power and to avoid erroneous readings:
³ Always inspect fiber ends and make sure that they are clean as
explained below before inserting them into the port. EXFO is
not responsible for damage or errors caused by bad fiber
cleaning or handling.
³ Ensure that your patchcord has appropriate connectors. Joining
mismatched connectors will damage the ferrules.
To connect the fiber-optic cable to the port:
1. Inspect the fiber using a fiber inspection microscope. If the fiber is
clean, proceed to connecting it to the port. If the fiber is dirty, clean it as
explained below.
2. Clean the fiber ends as follows:
2a. Gently wipe the fiber end with a lint-free swab dipped in isopropyl
alcohol.
2b. Use compressed air to dry completely.
2c. Visually inspect the fiber end to ensure its cleanliness.
Single-Ended Dispersion Analyzer 37
Operating the Single-Ended Dispersion Analyzer
Cleaning and Connecting Optical Fibers
3. Carefully align the connector and port to prevent the fiber end from
touching the outside of the port or rubbing against other surfaces.
If your connector features a key, ensure that it is fully fitted into the
port’s corresponding notch.
4. Push the connector in so that the fiber-optic cable is firmly in place,
thus ensuring adequate contact.
If your connector features a screwsleeve, tighten the connector
enough to firmly maintain the fiber in place. Do not overtighten, as this
will damage the fiber and the port.
Note: If your fiber-optic cable is not properly aligned and/or connected, you will
notice heavy loss and reflection.

Maintenance
Recalibrating the Unit
Recalibrating the Unit
Manufacturing and service center calibrations are based on the
ISO/IEC 17025 Standard, which states that calibration documents must not
contain a recommended calibration interval, unless this has been
previously agreed upon with the customer.
Validity of specifications depends on operating conditions. For example,
the calibration validity period can be longer or shorter depending on the
intensity of use, environmental conditions and unit maintenance. You
should determine the adequate calibration interval for your unit according
to your accuracy requirements.
Under normal use, EXFO recommends calibrating your unit every year.
