NOTE
The cables connected to the Tx Ports must not be removed following calibration.
If field calibration was not successful, implement the following measures:
• Check correct connection of launch cords.
• Check launch fiber connections for contamination. If necessary, clean connections
and check with a fiber test microscope (IDEAL order number 45-332).
• Dirty launch fibers also contaminate the measuring adapter connections. Clean
the connections on the FiberTEK™ III measuring adapters with an optical cleaning
sponge.
•
Check launch cords with a fiber continuity tester (IDEAL order number: VFF5) for
continuity.
• Replace suspected damaged launch cords.
