Optical Fiber Cord
Securing the Cord or Cable
Note It is good practice to leave about 2 or 3 meters of spare cable before each
Gently unreel the Optical Fiber Cable at less than 10 m/min by spinning the
reel, so that no pulling tension is applied to the Optical Fiber Cable itself. Be
sure not to apply any force to the cable (tension, bending, compression,
twisting, or impact) during installation that exceeds its maximum specifica-
tions.
The minimum bend radius for an Optical Fiber Cable during installation is
200 mm (20 times the cable diameter). Use a a tool such as a pulley at
bends of the cable to ensure that the bends exceed the minimum radius.
When installing straight sections, use pulleys as guides to ensure that the
tension on the cable does not exceed the maximum value. Set the pulleys no
more than 25 meters apart and allow the cable to sag at least 0.5 m.
Use a tension meter to monitor the tension in the cable if it is suspected to be
too high, and pull the cable along the installation route by hand or other
means if the tension is found to be too high.
node connection. This margin of cable allows room for attaching the connec-
tor and some repositioning of the node.
After laying the Optical Fiber Cord or Cable along the installation route, remove
the tape or tube used to protect the end of the cable. If a ferrule is going to be
attached to the end of the cable, clean the end of the ferrule surface with water
and wipe it with a soft, clean, and lint-free cloth or paper towel.
When installed in a rack or trough, secure the cord gently with mounting brackets
or saddles to prevent movement. Be sure not to attach the brackets or saddles
too tightly, because excessive compression will damage the cord.
At the last mounting bracket, bushing, or saddle, protect the cord with a rubber
ring, strip of rubber, or a few layers of PVC tape and secure it. Leave enough
slack in the cord to attach and remove the connector or move the node, if neces-
sary.
