Procedures To Be Followed In Fibre Optic Cable Installation

By Deanne Shepard


Fibre optic cable consists of bundles of extremely pure glass threads that is used to transmit data modulated onto beam of light waves. The cable can be easily damaged if it is improperly handled or installed. Special care is therefore required during fibre optic cable installation to ensure reliable operation.

The placement of the fibre cable in either indoors or outdoors environments follows basic guidelines that must be followed to ensure proper handling, placement, smooth operation and possible easier maintenance in future.

Before you commence on the procedure, you first need to carry out a site survey to enable you recognize the impending difficulties that may be experienced during the process. Possible risks prospects such as problems in controlling machinery or unfavorable climatic conditions ought to be taken into consideration to enable proper cabling. Moreover, building code laws must be noted. Existence of any queries relating to site building codes and laws, should be brought to the attention of courts.

A comprehensive design before diving in to deployment is then done. This involves establishing criteria for deployment, with regards to the communication paths required, evaluating total hardware requirements, lengths of cable and finally coming up with a breakdown list of hardware components required and specific places they will be used.

Formulate a wire pulling strategy. The system should represent the deliberations taken in during the site survey to the deployment team. For example, the location of transitional access points, the procedures of securing wires and other operating equipment and defined tasks of every individual of the team performing deployment.

Appropriate measures ought to be adhered to. Fibres being so susceptible, the end of cable should be covered with a cap or heavily taped throughout to prevent entry of moisture. The dents should not be left unattended to in the pull process because excess or difficult pulls, center-pull or back feeding techniques may be utilized.

The wires minimum bend radius should not be topped. When doing the placement, it is of essence not to bend to a radius that is beyond its original radius value. Immediately after its installation, and removal of the pulling tension, it cannot be bent to a radius other than the original radius that was defined. The cable is allowed to undergo alterations provided there is no desecration of the lowest bend radius limitations.

Maximum Recommended Load should never be surpassed during any stage of cable deployment. Each wire has a specific strength rating, hence upon placement completion the outstanding tension on the cable should always be less than this value.

It is always a common exercise to ensure you leave an extra cable at both the start and end of the optic wire run. In addition to this, an extra cable should be placed at strategic points to ensure smooth and reliable operation.

Finally, doing documentation of your procedural steps in an ordered and simplified manner is encouraged. It helps give assurance of properly deployment and in case of any elevation and future troubleshooting, there will always be a point of reference.
