Performing Automated IL/ORL/Length Measurements (FasTesT)

36 FTB-3930

Setting Up the FasTest

You can configure the FASTEST on the master unit only. The remote unit will

automatically adapt to these parameters (F

ASTEST parameters on remote

unit are ignored).

Setup includes the following elements:

 Port and DUT (fiber) type: multimode FASTEST will not include ORL.

 Compatibility: select FOT-930 / FTB-3930 for fast, two- or

three-wavelength testing including ORL (it requires two

FOT-930/FTB-3930). Use FOT-920 / FTB-3920 when other unit is an

FOT-920 or FTB-3920.

 Mode/wavelengths: select one or more wavelengths for the FASTEST.

Depending on your choice, the F

ASTEST will include loss and/or ORL

measurements. Selecting FTTx Custom or FTTx All allows you to

define upstream and downstream wavelengths.

 Unit location: in FTTx mode, you specify if the master unit is closer to

the CO (or to the premises) than the remote unit.
