Fiber optic cable care

Although the glass fiber in fiber optic cable is protected with reinforcing material and plastic

insulation, it is subject to damage. Use the following precautions to avoid damaging the glass

fiber.

• Do not kink, knot, or vigorously flex the cable.

• Do not bend the cable to less than a 40 mm radius.

• Do not stand on fiber optic cable; keep the cable off the floor.

• Do not pull fiber optic cable harder than you do a cable containing copper wire of

comparable size.

• Do not allow a static load of more than a few pounds on a section of the cable.

• Place protective caps on fiber optic connectors that are not in use.

• Store unused fiber optic patch cables in a cabinet, on a cable rack, or flat on a shelf.

Frequent overstressing of fiber optic cable causes progressive degeneration that leads to

failure.

If you suspect damage to a fiber optic cable, either due to mishandling or an abnormally high

error rate observed in one direction, reverse the cable pairs. If the high error rate appears in

the other direction, replace the cable.

Caution:

Risk of equipment damage

Do not crush fiber optic cable. If fiber optic cable is in the same tray or duct with large, heavy

electrical cables, it can be damaged by the weight of the electrical cable.

Fiber optic connector care

Before connecting fiber optic connectors to transmission equipment, test equipment, patch

panels, or other connectors, ensure fiber optic connectors are clean. The performance of an

optical fiber connector depends on how clean the connector and coupling are at the time of

connection.

A damaged or dirty connector can damage a connector with which it pairs. A connector must

be absolutely clean before you insert it into a transmitter or receiver.

Never clean an optical connector while it carries light. Optical power can cause ignition of the

cleaning material when it contacts the end of the optical connector and destroy the connector.
