Fiber Optic Connector Care - Nortel 4526 Installation Manual

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.

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.
If a connector performs poorly after cleaning, visually inspect the connector
to determine the possible cause of the problem and to determine if it needs
replacing.
Perform the following maintenance procedures to ensure that optical fiber
assemblies function properly. To prevent them from collecting dust, make
sure connectors are covered when not in use.

CAUTION
Risk of equipment damage
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.
WARNING
Risk of eye injury
Do not look into the end of fiber optic cable. The light source used
in fiber optic cables can damage your eyes.
To avoid getting debris in your eyes, wear safety glasses when
working with the canned air duster.
To avoid eye irritation on contact, wear safety glasses when
working with isopropyl alcohol.
CAUTION
Risk of equipment damage
To prevent further contamination, clean fiber optic equipment only
when there is evidence of contamination.
To prevent contamination, make sure the optical ports of all active
devices are covered with a dust cap or optical connector.
To avoid the transfer of oil or other contaminants from your fingers
to the end face of the ferrule, handle connectors with care.
