Optical coupler for connecting fiber optic cables

At present, fiber-optic communication lines have received the widest distribution, but they can not be carried out without such details as an optical coupler. With its help the connection of cable sections is carried out. It must perform a protective function to protect the welding site from environmental influences. In addition, the responsibility of this element is to protect the cable from ruptures and other loads on the line.

However, in the modern world optical couplings are not limited to the fulfillment of the above tasks. Currently, they are increasingly required to perform a switching function, helping to remove some of the fibers for connecting special equipment.

Today, the optical coupler must meet high requirements, which can vary widely. It all depends on the individual characteristics of certain types of couplings, but still it is possible to identify the basic requirements. First of all, the design of the product should be reliable and rational, while the simplicity of installing optical fibers is fundamental . Also, in no case should there be difficulties in the process of maintenance and operation.

To protect the welding places and the transit loop, an optical passage is often used. Its design allows the splice of several cables. In addition, it becomes possible to output a certain number of fibers to a particular network equipment. Due to the increased internal space, it is possible to arrange transit modules taking into account all the tolerances. It is allowed to install communication in the sewage mines, underground, on suspensions, poles and even on vertical surfaces.

Another version is an optical dead end coupler. Its features include a well-organized internal device, the ability to remove fibers without disconnecting the basic trunk cable, as well as the originality of the sealing. Many products are equipped with a special plastic case to help protect them from sudden temperature changes, aggressive environmental influences and excessive moisture. Usually a mechanical clamp is used, which helps to fix the two parts. Quality sealing can be achieved by means of a rubber ring placed around the perimeter.

Also, the optical clutch can be universal, representing an economical and multifunctional element. In this case, the two base parts are tightened with screws. The installation of all couplings is carried out in strict accordance with the instructions created for a certain type of product. During the installation work, the cable ends are fed into special closed machines having devices for their connection. After the end of installation, each element is supplied with a special marking ring, which is usually made of plastic or lead. It must specify the product number, brand OK and the name of the organization that conducted the work.
