Purpose
For optimum router performance, verify the condition of the cables that connect to the network ports.
Action
On a regular basis:
• Place excess cable out of the way. Do not allow fastened loops of cable to dangle from the
connector, 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 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
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.
