2. Cable management:
• Leave at least 4.6 m (15 ft) of cable at each end for future growth.
• Use strain reliefs to prevent the weight of the cable from damaging the
connector.
• Review all information in this manual and in any related manuals about safely
handling fiber-optic cables.
3. Connector protection:
• Insert connectors carefully to prevent damage to the connector or fiber.
• Leave the connector’s protective cover in place until you are ready to make
connections.
• Replace the connector’s protective cover when the connector is disconnected.
• Clean the connector before making a connection. Make sure that there are no
obstructions and that keyways are aligned.
Fiber-optic Cable Handling
Observe these precautions when you handle fiber-optic cables:
• Do not coil the cable to less than 96 mm (3.75 in.) in diameter.
• Do not bend the cable to less than 12 mm (0.5 in.) in radius. It is most important that
a cable’s bend radius be no less than 20 times the diameter of the cable.
• Do not pull on the cables; carefully place them into position.
• Do not grasp the cables with pliers, grippers, or side cutters; do not attach pulling
devices to the cables or connectors.
• Keep cables away from sharp edges or sharp protrusions that could cut or wear
through the cable; make sure that cutouts in the equipment have protective edging.
• Protect the cable from extreme temperature conditions.
• Install the connector’s protective cover whenever the connector is not connected.
