Placement and spacing place pull and splice boxes as shown in the plans and at the following locations unless directed otherwise by engineer. When pulling cable out from a conduit or ceiling it will become necessary to coil up the cable in preparation to pull it in another direction. Special fiber optic blocks should be used on all turns or angles. And always use a swivel pulling eye because pulling tension will cause twisting forces on the cable.

Boxes used with optical cables shall be designed for the purpose and shall be equipped with cable supports. Pull boxes shall be sized so that no cables in the box shall be tightly bent. 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 basic approach to pulling fiber optic cable and copper cable is similar. During the process installers should avoid cable damage despoiling the fiber properly and take pulling force into account. Loops of cable commonly called service loops shall be provided at all.

Since the real fiber pulling environment could be more complex the recommended procedures we offered above is a simple. However optical fiber has a few idiosyncrasies. 2d do make every effort to pull cables from a conduit in as straight an angle as possible. 5 use a swivel when pulling to make sure twists in the pull rope are not translated to the fiber optic cable.

Fiber optic pull box polycrete features 10k or 20k polymer concrete is lighter than traditional precast concrete but offers higher compressive strength for increased durability. 2e how to handle slack.
