Maintaining Fiber-Optic Cables in EX Series Switches

To maintain fiber-optic cables:
•
When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over
the transceiver and on the end of the cable.
•
Anchor fiber-optic cables to avoid stress on the connectors. When attaching a
fiber-optic cable to a transceiver, be sure to secure the fiber-optic cable so that it is

free from the connector.
•
Avoidbendingfiber-opticcablesbeyondtheirminimumbendradius.Bendingfiber-optic
cables into arcs smaller than a few inches in diameter can damage the cables and
cause problems that are difficult to diagnose.
•
Frequentpluggingandunpluggingoffiber-opticcablesinandoutofopticalinstruments
can damage the instruments, which are expensive to repair. Attach a short fiber
extension to the optical equipment. Any wear and tear due to frequent plugging and
unplugging is then absorbed by the short fiber extension, which is easier and less
expensive to replace than the instruments.
•
Keep fiber-optic cable connections clean. Micro-deposits of oil and dust in the canal
of the transceiver or cable connector cancause loss of light, reduction in signal power,
and possibly intermittent problems with the optical connection.
