FIBER CHARACTERIZATION SCRIPT
GETTING STARTED
The following procedure describes how to configure a T-BERD/MTS 8000 platform with a MTAU 4-port module and how to start the
Automated Fiber Characterization Script. Please read the entire procedure BEFORE starting.
Inspect and clean connectors
Before connecting a fiber into a test module, inspect and clean the module bulkhead and the fiber jumper connectors.
!
-
Use video inspection scope to verify the connector quality.
-
Use appropriate cleaning material (e.g. IBC™ cleaner, cotton swab, dust air sprays, etc...).
Connecting the test modules to the MTAU
Connect the OTDR module to the MTAU port A with a jumper.
1
Connect the OFI module (FOX port) to the MTAU port B with a jumper.
2
3 Connect the DISPAP module to the MTAU port C with a jumper.
Connect the BBS module to the MTAU port D with a jumper.
4
DISPAP (CD/PMD/AP)
The test modules (OTDR, DISPAP and OFI) have to be located in the slots closest to the mainframe. Keep the MTAU and BBS
modules at the back slots.
Repeat step 1 and 4 for the second unit.
5
Referencing the Test Functions
The Insertion Loss (IL), the Optical return Loss (ORL), the Chromatic Dispersion (CD) and the Attenuation Profile (AP)
1
measurements have to be referenced before starting testing.
Please refer to dedicated quick cards for the associated procedures
