Referencing the test functions

The test modules (OTDR, DISPAP) have to be located in the slots clos-

est to the mainframe. Keep the MTAU module at the back slots.

Referencing the test functions

The following test functions require REFERENCING before performing tests:

FCOMP - Insertion Loss (IL) and Optical return Loss (ORL)

The IL/ORL Referencing is done to ensure that the IL and ORL of the fiber

jumpers are taken into account for an accurate qualification of the fiber to test.

Chromatic Dispersion (CD), Attenuation Profile (AP)

The AP /CD referencing is done to ensure that the far end broadband source is

calibrated with the DISPAP module and the insertion loss of the fiber jumpers are

taken into account for an accurate qualification of the fiber to test.

This measurement is a two ended test. Both T-BERD/MTS 8000 V2 Platform

and Broadband Source (OBS Handheld or T-BERD/MTS including the BBS

capability) must be at the same location

Before connecting a fiber into a test module, inspect and clean the module bulkhead and

the fiber jumper connectors.

Use the P5000i video inspection scope to verify the connector quality.

Use appropriate cleaning material (e.g. IBC™ cleaner, cotton swab, dust air

sprays, etc...) and re-inspect to confirm.
