Handling and cleaning fiber optic equipment
Precautions
Although the glass optical path of 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 (1.5-inch) radius.
• Do not stand on fiber optic cable; and keep the cable off the floor.
• Do not pull fiber optic cable any harder than you would a cable containing
copper wire of comparable size.
• Do not allow a static load of more than a few pounds on any 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.
Danger: Do not look into the end of fiber optic cable. The light source used in
fiber optic cables can damage your eyes.
Warning: To prevent damage to the glass fiber, make sure you know how to
handle fiber optic cable correctly.
Warning: 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.
