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.
The preliminary step in the connection process is to conduct a site survey. The purpose of the survey is particularly to familiarize with the place and to recognize the circumstances and locations that require special attention. During the survey, physical hazards, including high temperatures and operating machinery are noted to enhance planning for cable routing accordingly. The visit also enables you to consider and appreciate the building code regulations and have any questions addressed by the relevant authority within the jurisdiction, including the fire marshal and city building inspector.
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.
During this practice, remember to follow the proper procedures. Fibers are sensitive to moisture and thus their ends must be covered using an end cap or heavy tape at all times. When carrying out a pull, never leave the let-off reel unattended as difficult pulls, back-feeding or center-pull techniques may be used.
During the exercise, be sure not to exceed the minimum bend radius. Remember that every wire poses a minimum installation bend radius value. When placing them, it is important not to bend the cables to a smaller radius. On installing and after removing the pulling tension, they may only be bent to a radius not smaller than the specified long term application length of the radius. Coiling and wrapping is allowed as long as it does not violate the constraints of minimum bend radius.
Another important factor to consider is the maximum recommended cable length. Despite the fact that fiber optics are much stronger compared to copper wires, it is imperative not to exceed the maximum tension pulling. The general strength ranking for most outdoor cables is 2700N.
The residual tension after placement must be less than this specified value. In case of vertical connections, it is advised that the optic wires be clamped at regular intervals to avoid its weight from surpassing the recommended load on the long term. However, the clamping intervals must be adequate to avoid cable movement and provide weight support.
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.
