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.
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.
The second step is to plan for the cable pulling. The plan incorporates the findings made in the survey stage and serves as a communication tool for the connection team on the considerations noted. It integrates the logistics of pulling equipment, splice locations and the locations of intermediate access points. Also, it is important to detail the particular duties and responsibilities of every individual member in the fixation team.
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.
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.
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.
