Enhancing An Effective Fibre Optic Cable Installation

By Sherry Gross


Fiber optics that has been improperly placed is susceptible to damage. In order to enhance handling and good performance, it is imperative that some procedures and guidelines be followed in the connection of these cables to prevent damage and limiting their usefulness. This article, therefore, takes you through the pertinent issues and facts during 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 effectiveness of the connection largely depends on the length of the bend radius. There is always a minimum value specified for the bend radius; ensure to observe this value. Bending them to smaller radius than this value is inappropriate. The same value applies when coiling or wrapping the cable. There is no significant limit with regards to coiling, but be sure to do it within the constraint of the minimum bend value.

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.

The maximum load value is also a matter worth your concern for long term application. There is a set upper load value for long term performance. Always ensure that the remaining tension after connection is less than the maximum value. For those engaged in vertical clamping, clamp the cables such that the interval between them is regular and sufficient to ensure that the weight remains within the set limit.

Finally, it is necessary to document the process. A good record keeping is important as it ensures that the process is done correctly and simplifies future upgrading and troubleshooting. Record the special lot number labeled on the shopping spool. Both pre and post installation test information should be recorded in a logical and orderly manner.
