How long should the optical cable be pulled out of the optical distribution box
The cable should be bent as little as possible. Avoid pulling cables over edges. The maximum installation. You should pull on the fiber cable strength members only! Never exceed the maximum pulling load rating. On long runs, use proper lubricants and make sure they are compatible with the cable jacket. The connector/cable. Most fiber optic cables boast a pull strength of 100 – 200 pounds thanks to the internal kevlar or aramid yarn, known as the strength member. Many installers pull fiber by the outer jacket which is prone to. Check the cable length to make sure the cable being pulled is long enough for the run to prevent having to splice fiber and provide special protection for the splices. Try to complete the installation in one pull. For more information, reference the EIA/TIA 568A Spec and the IEEE 802.
