Multifunction Loss Tester 35

7 Performing Automated

IL/ORL/Length Measurements

(FasTesT)

FASTEST allows you to perform 2- or 3-wavelength bidirectional loss and

ORL tests for singlemode fibers, or 2-wavelength loss tests for multimode

fibers, in 10 seconds (including fiber length measurement).

ASTEST is useful in high-fiber-count installations. Activated at the touch of a

button, F

ASTEST cuts down on training time and provides error-free results.

To use F

ASTEST, you need a compatible unit (such as FTB-3930, FOT-930,

FOT-920 or FTB-3920, but not the FOT-910). The unit at the remote end is

only used to establish references. It then waits for commands from the unit

initiating F

ASTEST (master).

The F

ASTEST procedure is outlined below:
