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.

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.

Inserting and Removing Test Modules

CAUTION
Never insert or remove a module while the FTB-500 is turned on. This will result in immediate and irreparable damage to both the module and unit.
WARNING
When the laser safety LED ( ) is flashing on the FTB-500, at least one of your modules is emitting an optical signal. Please check all modules, as it might not be the one you are currently using.
To insert a module into the FTB-500:
1. Exit ToolBox and turn off your unit.
2. Position the FTB-500 so that its right panel is facing you.

Setting up Application Details

You can customize the distance units, the CD display values and whether or not you are warned each time a scan is complete.
You can also keep the intermediate data when performing tests. This option should be used when there is a problem with the Single-Ended Dispersion Analyzer or a measurement. Once you have acquired this intermediate data, which represents all of the actions done by the unit when performing the test, you can take this file and send it to EXFO for troubleshooting purposes.
IMPORTANT
Selecting the Keep intermediate data option will increase the size of your result file in a significant manner.
