Fiber Optic Cable Pull Box

Then position the pulling grip over the cable core and tape it in place.

Fiber optic cable pull box.

The basic approach to pulling fiber optic cable and copper cable is similar. Loops of cable commonly called service loops shall be provided at all. Also use a tensionmeter to monitor the tension being applied to the cable during the pull. 2e how to handle slack.

5 use a swivel when pulling to make sure twists in the pull rope are not translated to the fiber optic cable. Placement and spacing place pull and splice boxes as shown in the plans and at the following locations unless directed otherwise by engineer. During the process installers should avoid cable damage despoiling the fiber properly and take pulling force into account. And always use a swivel pulling eye because pulling tension will cause twisting forces on the cable.

However optical fiber has a few idiosyncrasies. The number of 90 degree turns on a pull shall not exceed 6 for aerial cables and 4 for underground cable in conduit. Pulling fiber optic cable is a dispensable and rather important part in fiber cable installation. Fiber optic cable has a memory.

Pulling on an angle can cause damage to the cable. Since the real fiber pulling environment could be more complex the recommended procedures we offered above is a simple. Pull boxes shall be sized so that no cables in the box shall be tightly bent. A length of free cable shall be provided at each end of a cable pull.

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. Boxes used with optical cables shall be designed for the purpose and shall be equipped with cable supports.

The most common damage is a broken fiber which is difficult to detect. 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. 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.

Special fiber optic blocks should be used on all turns or angles.
