Fiber Cable Pull Box

Otherwise the jacket may be stretched in the pull and the fiber can bunch up beneath the jacket when tension is released.

Fiber cable pull box.

Also use a tension meter to monitor the tension being applied to the cable during the pull. Placement and spacing place pull and splice boxes as shown in the plans and at the following locations unless directed otherwise by engineer. Caution shall be taken to coil the fiber cable per manufacturer s recommendations. Providing teldor fiber a world class cable manufacturer utilizing corning glass smf 28e.

At all major fiber optic cable and conduit. Fiber optic cables have kevlar aramid yarn or a fiberglass rod as their strength member. Pull boxes shall be sized so that no cables in the box shall be tightly bent. Polycrete features 10k or 20k polymer concrete is lighter than traditional precast concrete but offers higher compressive strength for increased durability.

Browse products like concrete cast pull boxes covers accessories and non metallic pull boxes to find the perfect item for any job or situation. 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. Fiber optic pull box. The most common damage is a broken fiber which is difficult to detect.

A length of free cable shall be provided at each end of a cable pull. Lateral cable to be coiled in each pul box. Plastic wire ties shall not be allowed. The load must be applied to the strength bearing members of the cable.

Never exceed the maximum pulling load rating. Fiber optic cable coils within pull boxes shall be tied to each cable rack. On really long runs pull from the middle out to both ends. You should pull on the fiber cable strength members only.

On long runs use proper lubricants and make sure they are compatible with the cable jacket. The basic approach to pulling fiber optic cable and copper cable is similar. 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. 13 pull box types as depicted on this project detail sheet shall not be installed in the asphalt or.

The cables minimum bending radii shall not be violated. However optical fiber has a few idiosyncrasies. Loops of cable commonly called service loops shall be provided at all intermediate pulling points such as in manholes and pull boxes.
