Fiber-optic Cable Installation
Follow these guidelines when you install fiber-optic cables:
1. Cable routing:
• Raised floor: You may install fiber-optic cables under a raised floor. Route
them away from any obstruction, such as existing cables or other equipment.
• Cable tray or raceway: Place the cables in position; do not pull them
through the cable tray. Route the cables away from sharp corners, ceiling hangers,
pipes, and construction activity.
• Ver tical rise length: Leave the cables on the shipping spool, and lower them
from above; do not pull the cables up from below. Use proper cable ties to
secure the cable.
• General: Do not install fiber-optic cables on top of smoke detectors.
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. StorageTek
recommends 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.
