Fiber Cable Pull Box

On really long runs pull from the middle out to both ends.

Fiber cable pull box.

Also use a tension meter to monitor the tension being applied to the cable during the pull. A simple way to avoid this is to tie a knot at the pulling end of small fiber optic cables. Otherwise the jacket may be stretched in the pull and the fiber can bunch up beneath the jacket when tension is released. On long runs use proper lubricants and make sure they are compatible with the cable jacket.

Polycrete features 10k or 20k polymer concrete is lighter than traditional precast concrete but offers higher compressive strength for increased durability. The cables minimum bending radii shall not be violated. Pull boxes shall be sized so that no cables in the box shall be tightly bent. Providing teldor fiber a world class cable manufacturer utilizing corning glass smf 28e.

You should pull on the fiber cable strength members only. 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. 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.

Lateral cable to be coiled in each pul box. Fiber optic pull box. Browse products like concrete cast pull boxes covers accessories and non metallic pull boxes to find the perfect item for any job or situation. Fiber optic cable coils within pull boxes shall be tied to each cable rack.

However optical fiber has a few idiosyncrasies. Placement and spacing place pull and splice boxes as shown in the plans and at the following locations unless directed otherwise by engineer. 13 pull box types as depicted on this project detail sheet shall not be installed in the asphalt or. Refine your search with our convenient filtering options at the top of the page.

A length of free cable shall be provided at each end of a cable pull. The load must be applied to the strength bearing members of the cable. 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.

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