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 prevent stress on the connectors. When attaching a
fiber-optic cable to a transceiver, be sure to secure the fiber-optic cable so that it does
not support its own weight as it hangs to the floor. Never let a fiber-optic cable hang
free from the connector.
Avoid bending fiber-optic cables beyond their minimum bend radius. Bending fiber-optic
cables into arcs smaller than a few inches in diameter can damage the cables and
cause problems that are difficult to diagnose.
Frequent plugging and unplugging of fiber-optic cables in and out of optical instruments
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. Microdeposits of oil and dust in the canal of
the transceiver or cable connector can cause loss of light, reduction in signal power,
and possibly intermittent problems with the optical connection.
To clean the transceiver canal, use an appropriate fiber-cleaning device such as
RIFOCS Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions
in the cleaning kit you use.
After cleaning the transceiver, make sure that the connector tip of the fiber-optic
cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit such
as the Opptex Cletop-S
use.
