Enhancing An Effective Fibre Optic Cable Installation

By Sherry Gross


In an attempt to enhance reliability and performance of optical fibers, special care is paramount, especially in the process of installation. Some crucial guidelines regarding tensile loads, squeezing, minimum bend radius, and twisting must be considered. As a matter of fact, connectors must be protected free from scratching and contamination at all times. Close attention must be paid to these factors as violation of any parameter causes profound attenuation and damage to the conection. It is therefore worth considering the following insights on fibre optic cable installation.

When planning for the placement, begin by carrying out a site survey. This preliminary visit of the site is intended to familiarize you with the general conditions and ascertain the specific locations and circumstances that call for special attention. The survey entails identifying potential challenges such as high temperatures, weak walls and operating machinery to help provide for them well in advance during routing. In addition, this stage enables you to get acquainted with the building code and regulations in place and to seek for clarification from the relevant resource person concerning the same.

After surveying, you then develop an effective cable pulling plan. The plan ought to communicate to the fixation team the considerations noted in the site survey. It entails logistics on cable let-off or pulling equipment, splice and intermediate access point locations. In addition, the plan must outline the particular responsibilities of each and every member of the team involved in the fixation.

When undertaking the exercise, it is vital to follow the required procedure. Due to their delicate nature when exposed to moisture, the end of the cables must be insulated by an end cap at all times. The process of pulling should not be done when the left-off reel is unattended to since center-pulls, back-feeding and difficult pull techniques may be applied.

The connection should put in mind the minimum bend radius. It is crucial to consider the fact that every connector has its own minimum radius value. Therefore, be sure not to curve them more than the recommended bend value. The specified long range application radius must be adhered to during placement and after eliminating the pulling tension. As a general rule, wrapping and coiling is acceptable, but only when done within the constraints of the bend radius.

Just like the minimum radius, there is also a constraint on the maximum length. Fiber optic comes stronger than copper, however, the length of the optic connector must be maintained lower than the maximum recommended length during all phases of installation. The average strength ratings of many connectors stand at 2700 N.

Apart from the cable length, there is also the uppermost load value recommended in the long run. As such, the resultant tension after the placement should be less than this value. When installing vertically, be keen to clamp the wires at consistent intervals in order to avoid the resulting weight from exceeding the specified long-term load. Nevertheless, the intervals between clamps must be enough to prevent movement and support the weight.

Ensure to document each phase of fixation. Documentation of the same provides a record for future reference and maintenance. The task of documentation should be done systematically to enhance flow and order. When in need of whatever type of connection, remember to check out on the above points.
