Underground installation cable

Underground Fiber Optic Cable Installation. Obtain proper right-of-way permits. Identify existing underground utilities such as buried cables, pipes. Investigate the soil condition in order to determine the installation depth, the type of fiber cable should be used, and the plowing equipment needed. DO NOT use detergent or petroleum based compounds as a cable lubricant. NEVER set a cable reel on a flange side to prevent cable crossings during payoff. First, identify the innerduct in which the fiber optic cable is to be placed.

After the correct innerduct has been identified, it should be tied off to keep it from "creeping" as the cable is being pulled into it. Any spare ducts should be capped off so that they do not interfere with the cable pulling operation.

Prepare the pull-through manholes. This includes un-racking the innerduct and removing slack caused by the racking, placing lubricant where appropriate, preparing the pulling line and usually re-coupling the innerduct to provide a continuous path for the cable to follow. The amount of lubricant used in intermediate manholes will depend on the length between manholes, type of innerduct, etc.

Position the pulling equipment winch or capstan at the pulling manhole. Never exceed the pound pulling limit of the cable. At the pull end manhole, install the proper guides specified by your company's practices. These guides are to ensure that the pull line and fiber optic cable enter and exit the innerduct in a straight path. And intermediate manholes should be prepared for the cable pull by having any problems that were observed during the pre-pull survey already sorted out. Position the cable reel adjacent to the feed manhole so that the cable can be hand-fed in the manhole.

Safety Software. The noise around short interval control and smart data flows from underground mining fronts continues to grow. Now you are ready to extend cable into the house and into the garage and complete the hookups. Make sure that all wires are contained inside conduit as they pass through the walls of the house and garage and into the interior. After wiring the outlets and lights in the garage, the last step will be to connect the circuit breakers at the main service panel.
