FOCL inside one building. In this case, a two-fiber OK (“Noodle” type) is used for communication, which, if necessary, can be laid in the PND-32 tube under a raised floor or along walls in decorative boxes. All work can be done by the customer himself if the supplied cable is terminated with appropriate connectors.
fiber optic certification
FOCL between buildings is built with a wok laying either along with the wells of cable communications or by hanging a wok between supports. In this case, it is necessary to ensure the coupling of a thick multi-fiber cable with optical transceivers. For this, cable sleeves are used in which the ends of the wok are cut, the fibers are identified and the fibers are terminated with connectors corresponding to the selected transceivers. This work can be done in several ways.
You can order a wok in a special performance Break-Out. This is a more expensive option, but you can immediately terminate the cable with optical connectors, remove terminated modules (cords similar to mounting wires) from the coupling and connect them to the transceiver equipment.
Optical cords with pigtail connectors can be welded to the fibers cut into the cable box. The length of the pigtail is selected for reasons of convenience for the user (for example, 3 m).
It is possible to terminate the fibers with connectors and plug the connectors from the inside into optical sockets (coupling) mounted in the wall of the cable box. Outside, an optical cord connector is inserted into the coupling leading to the transceiver equipment.
There are other ways to connect the wok with optical transceivers. Each method has its own advantages and disadvantages. In the practice of VIACOM OPTIC specialists, the third method has spread, since it is economical, reliable, provides low insertion optical losses through the use of sockets and connectors with ceramic elements, and is also convenient for users.
Special mention should be made of the need for optical cross-connect.
It should be noted that in recent years several methods for splicing optical fibers have been developed. Universal is considered a method of splicing fibers by welding on a special apparatus. Such devices are produced by firms: BICC (Great Britain), Ericsson (Sweden), Fujikura, Sumitomo (Japan). The high cost of welding machines has led to the creation of alternative technologies for splicing optical fibers.
