Fiber Optic Cable Pull Box

Number of 90 degree turns.

Fiber optic cable pull box.

Pulling fiber optic cable is a dispensable and rather important part in fiber cable installation. 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. Pulling on an angle can cause damage to the cable. Also use a tensionmeter to monitor the tension being applied to the cable during the pull.

Boxes used with optical cables shall be designed for the purpose and shall be equipped with cable supports. Since the real fiber pulling environment could be more complex the recommended procedures we offered above is a simple. The most common damage is a broken fiber which is difficult to detect. 5 use a swivel when pulling to make sure twists in the pull rope are not translated to the fiber optic cable.

Pull boxes shall be sized so that no cables in the box shall be tightly bent. 2e how to handle slack. 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. Placement and spacing place pull and splice boxes as shown in the plans and at the following locations unless directed otherwise by engineer.

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. A length of free cable shall be provided at each end of a cable pull. Pulling underground fiber optic cable.

During the process installers should avoid cable damage despoiling the fiber properly and take pulling force into account. Special fiber optic blocks should be used on all turns or angles. Refine your search with our convenient filtering options at the top of the page. However optical fiber has a few idiosyncrasies.

Then position the pulling grip over the cable core and tape it in place. And always use a swivel pulling eye because pulling tension will cause twisting forces on the cable. The number of 90 degree turns on a pull shall not exceed 6 for aerial cables and 4 for underground cable in conduit. Fiber optic cable has a memory.

Loops of cable commonly called service loops shall be provided at all.
