Fiber optic cable has become an excellent alternative to copper, because it's lighter, thinner and more durable. Installation of fiber optic systems is constantly being improved, and in this process, an important point is fastening.
How to choose fasteners for optical cable
Fastening must occur clearly according to the scheme in order to avoid damage to the fibers, that do not tolerate kinks, stretching and sagging. For this, special fittings are used - products, with which all parts of the fiber optic system are attached, providing secure fixation.
Traverses
Traverse - it's a mount, which is used to hang the cable. It is made of a metal corner with an anti-corrosion coating.. Fastening cables with their help is also an excellent protection of lines from rodents and any damage..
Traverse has, usually, multiple holes, allowing you to attach two or three parallel wires at once.
Tension clamps
These structures made of metal and plastic are wedge-shaped., through the base of which the cable passes. The main task of such fasteners is to provide a certain degree of tension.. Tension armature body made of plastic, which allows you to protect the contents from UV rays.
Support clamps
Clamps are most often attached to hooks, fixed on supports, and serve to adjust the required height and boom of the suspension line.
With such mounts, fiber optic systems can be mounted there, where the angle of the passing line does not exceed 25 degrees.
Hooks and brackets
To be able to use hooks and brackets indoors and outdoors, they are made of metal, corrosion resistant.
After all, it is precisely such fittings that take on virtually the entire load during the installation of fiber optic lines..
It can be of prefabricated or cast construction.. The latter is intended for installation of lines with increased load and possible mechanical influences from the outside..
As for the material, duralumin products have excellent characteristics.
Features of choice
Universal mounts for optical cables do not exist. Tension clamp or support, hooks and brackets, traverse buy which is better than carbon steel, or something different, must be decided on a case-by-case basis..
The choice of these products should be approached, considering the following parameters:
- Place of attachment (power lines, collectors, communication channels, walls).
- Mounting method (hanger or pad).
- Cable design:
- Diameter. Depending on this parameter, it is important to choose the correct size and distance between the fixing elements of the tension and support clamps., so that the cable does not slip, but it was not transferred.
- Hanging Distance. Based on distance, it will be clear, how many fasteners will be needed for the entire line.
- Cable weight. In order for the fastener to withstand the necessary load and mechanical external influences, cable weight must be taken into account. Otherwise, the situation with its break cannot be avoided..
Properly selected fittings for an optical cable will not only ensure its reliable fixation, and will prevent the need for constant repair of lines.
