Fiber Cable Pull Box

Loops of cable commonly called service loops shall be provided at all intermediate pulling points such as in manholes and pull boxes.

Fiber cable pull box. Polycrete features 10k or 20k polymer concrete is lighter than traditional precast concrete but offers higher compressive strength for increased durability. The most common damage is a broken fiber which is difficult to detect. Fiber optic cables have kevlar aramid yarn or a fiberglass rod as their strength member. On really long runs pull from the middle out to both ends.

13 pull box types as depicted on this project detail sheet shall not be installed in the asphalt or. Placement and spacing place pull and splice boxes as shown in the plans and at the following locations unless directed otherwise by engineer. A length of free cable shall be provided at each end of a cable pull. Never exceed the maximum pulling load rating.

The basic approach to pulling fiber optic cable and copper cable is similar. The glass fiber within the cable is fragile and although the cable has been designed to protect the fiber it can be damaged more easily than a copper wire. At all major fiber optic cable and conduit. On long runs use proper lubricants and make sure they are compatible with the cable jacket.

Providing teldor fiber a world class cable manufacturer utilizing corning glass smf 28e. Lateral cable to be coiled in each pul box. Ensure that pull and splice boxes house fiber optic cable without subjecting the cable to a bend radius less than 14 times the diameter of the cable. Caution shall be taken to coil the fiber cable per manufacturer s recommendations.

Also use a tension meter to monitor the tension being applied to the cable during the pull. Otherwise the jacket may be stretched in the pull and the fiber can bunch up beneath the jacket when tension is released. Plastic wire ties shall not be allowed. Fiber optic pull box.

However optical fiber has a few idiosyncrasies. After pulling fiber optic cable cut off approximately 10 feet of cable from the pulling end to remove any portion of the cable that may have been stretched or damaged during installation. Refine your search with our convenient filtering options at the top of the page. The load must be applied to the strength bearing members of the cable.

Fiber optic cable coils within pull boxes shall be tied to each cable rack. You should pull on the fiber cable strength members only. A simple way to avoid this is to tie a knot at the pulling end of small fiber optic cables.
