stresses the cable at the fastening point. Putting fasteners on the loops helps to
maintain their shape.
Keep the cable connections clean and free of dust and other particles, which can cause
drops in the received power level. Always inspect cables and clean them if necessary
before connecting an interface.
Label both ends of the cables to identify them.
The following guidelines apply specifically to fiber-optic cables:
When you unplug a fiber-optic cable, always place a rubber safety plug over the
transceiver on the MIC faceplate and on the end of the cable.
Anchor fiber-optic cables to avoid stress on the connectors. Be sure to secure fiber-optic
cables so that they do not support their own weight as they hang to the floor. Never
let fiber-optic cable hang free from the connector.
Avoid bending fiber-optic cable beyond its bend radius. An arc smaller than a few
inches can damage the cable and cause problems that are difficult to diagnose.
Frequent plugging and unplugging of fiber-optic cable into and out of optical
instruments can cause damage to the instruments that is expensive to repair. Instead,
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 easy and inexpensive to replace.
Keep fiber-optic cable connections clean. Small microdeposits of oil and dust in the
canal of the transceiver or cable connector could cause loss of light, reducing signal
power and possibly causing intermittent problems with the optical connection.
To clean the transceivers, use an appropriate fiber-cleaning device, such as RIFOCS
Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions for the
cleaning kit you use.
After you clean an optical 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 Fiber Cleaner. Follow the directions for the cleaning kit you
use.
