Use the cable management system (shown in
and prevent cables from dislodging or developing stress points.
Place excess cable out of the way in the cable management system. Do not allow
fastened loops of cable to dangle from the connector or cable management system,
because this 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 PIC cables to identify them.
The following guidelines apply specifically to fiber-optic cable:
When you unplug a fiber-optic cable from a PIC, always place a rubber safety plug
over the transceiver on the PIC faceplate and on the end of the cable.
Anchor fiber-optic cable to avoid stress on the connectors. When attaching fiber to a
PIC, be sure to secure the fiber so it is not supporting its own weight as it hangs 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, such as ATM or SONET/SDH analyzers, 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 micro-deposits 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.
