Optical fiber, as a medium for transmitting large amounts of information, is increasingly being used in the world and in our country in particular. Optical cable has an advantage over copper. However, its application also requires a number of difficult problems.
The difficulty is that the fiber optic laying must be approached with special care. We must not forget that no matter how armored the optical cable is, there is still glass inside it, with all its shortcomings. It can not be strongly stretched, bent and crushed. All these parameters are indicated in the passport for the cable, in the relevant regulatory documents and rules for laying FOCL (you can find a list of such documents at the end of the article).
The success of any fiber optic cable installation project depends on the implementation of the installation rules.
In general, the process of laying FOCL consists of preparatory and main stages.
As part of the first of them, a choice is made of the cable installation method: directly into the ground, sewerage, suspension on the lower traverse of a power transmission line or laying in a ground wire, installation under water or laying in an asphalt pavement, etc. Based on the decision made, the required type of cable is selected.
Before starting the laying of FOCL, the optical cable must necessarily pass the primary control. The primary control procedure will be described in detail in our other articles.
Next, you need to prepare a route for cable installation. This procedure includes the installation of the necessary devices to protect the cable during pulling from excessive bending and damage to the insulation. These can be various rollers, cable bends, guides, etc.
In some cases, for example, when laying a cable in a cable duct, it is necessary to prepare a channel. Depending on how the broach will be done.
