For optimum router performance, verify the condition of the PICs and PIC cables.
On a regular basis:
Use the cable management system to support cables 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.
