Care of fiber optic equipment
13
If you suspect damage to a fiber optic cable, either due to mishandling or
an abnormally high error rate observed in one direction, reverse the cable
pairs. If the high error rate appears in the other direction, replace the cable.

pairs. If the high error rate appears in the other direction, replace the cable.
CAUTION
Do not crush fiber optic cable. If fiber optic cable is in the same
tray or duct with large, heavy electrical cables, it can be damaged
by the weight of the electrical cable.

Fiber optic connector care
Before connecting them to transmission equipment, test equipment,
patch panels, or other connectors, clean all fiber optic connectors. The
performance of an optical fiber connector depends on how clean the
connector and coupling are at the time of connection. Use the following
cleaning procedures when analyzing fiber connector integrity.
