Single-Ended Dispersion Analyzer 1

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.

Module Description

Dispersion Analyzer

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.

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:

³The 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.

³You 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 69 for details).

Note: Other reflective terminations include mirror connectors, fiber pigtailed

mirrors, cleaved fibers. However, do not use fiber loop mirrors or

Faraday-type mir rors.

4FTB-5700

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:

³The FUT length must be terminated by a UPC connector.

³The FUT length must be less than 120 km.

³The 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.
