MultiTest Module 1
1 Introducing the FTB-3930
MultiTest Module
The FTB-3930 MultiTest Module integrates a power meter and light sources
with an optical return loss meter, optional talk set and visual fault locator.
Main Features
The unit features FASTEST™, EXFO’s one-touch automated measurement.
In 10 seconds, you can simultaneously test IL and ORL at up to four
wavelengths, in both directions. During the same test, the unit also
determines fiber length.
Note: Optical ports and connectors may differ from the illustration.

Main Features
The power meter has the following characteristics:
³Ge, GeX or InGaAs detector with 40 calibrated wavelengths to measure
absolute power or link loss
³Editable list of favorite wavelengths for easy access
³Modulated signal detection
³No offset nulling required in normal operation
The light source has the following characteristics:

³Customizable test thresholds with visual pass/fail analysis
³Transfer data from the FOT-930 Multifunction Loss Tester (using the
Handheld Data Transfer application) for easier management and
greater storage capacity
³Save your OLTS data in popular text formats (XML, ASCII, etc.) or
convert older result files to the new format for analysis
³Customize user settings and cable identification parameters
³Generate and print reports about OLTS data, including user and test
location information and operator comments
³FASTESTresults displayed according to FTTx usage and terminology
Typical Applications
You can use the MultiTest Module for several applications, such as:

3 Getting Started with Your
MultiTest Module
Inserting and Removing Test Modules
To insert a module into the FTB-400 Universal Test System:
1. Exit ToolBox and turn off your unit.
2. Position the FTB-400 so that its right panel is facing you.
CAUTION
Never insert or remove a module while the FTB-400 Universal Test
System 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-400, 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.

3. Take the module and place it so that the connector pins are at the
back, as explained and shown below.
³(2-slot or 4-slot receptacles) identification sticker must be on left
side and retaining screw hole under connector pins.
CAUTION
Inserting a module upside down could result in permanent damage
to the module, as the connector pins might be bent.
