Connecting Optical Fibers

The need to connect the optical fiber occurs when the construction of fiber-optic links (FOL), as well as the restoration of optical fibers after the accident. In some cases, welding is used to make some attenuation in optical fibers liniyu.Soedinenie requires very precise alignment, which can be run on the device as the core and shell of the fiber. This is necessary in order the entire light beam passes through the connection with minimal losses. There are two main methods of connecting optical fibers: Welding and mechanical soedinenie.Opticheskaya svarka.Dlya welding fibers applied optical welders. Our company has provided equipment from leading world manufacturers: Fujikura (Japan), Sumitomo (Japan), Furukawa (Japan), Corning (USA), Jilong (China). For detailed information about them can be found in relevant sections of the site splicers.ru. The optical connection is welding machines using electrical discharge (arc). This operation can be performed both in automatic and manual rezhime.Pered bonding an optical fiber must be prepared.

To begin, remove the protective cover from the fiber. For this purpose special tools. Then, the fiber must be cleaned from the remnants of the gel. After that produce chipping. Cleavage is necessary to ensure that the welded end of optical fiber has been completely smooth. Cleavage produces a special device, which is called – an optical fiber cleaver. There mass of instruments of this kind. Put together and free from dust and fat with alcohol wipes optical fiber is placed in a welding machine.

And fiber is welded to the selected rezhimom.Tipovoy welding machine consists of two clamps, which fit into the fiber, and two electrodes between which the arc electric discharge. Properly align the fibers and lay about each other built-in microscope and help screen, which displays the welding process. Devices with an arc discharge can weld up to 24 fiber ribbon odnovremenno.Bolshinstvo modern devices for welding optical fibers have automatic modes with the ability to custom programming, which facilitates the welding process. Built-in computer allows you to align the fibers with high accuracy and to choose the right discharge power, which allows us to achieve a high quality connection with the damping of no more than 0.02 optical dB.Sovremennnye welding allow you to make a given attenuation of the line. Loss to 10dB can be programmed with svarke.Mehanicheskie soediniteli.Mehanicheskie connectors allow to dispense with welding equipment. Loss of their use are of 0,5 dB to 0,75 dB. The most frequently used in the budget lines, or as a temporary replacement Welded soedineniyu.Kratky itog.Takim way, thanks to its compact size, versatility, high quality connections, machines for welding optical fibers are now indispensable tools for installation and maintenance of fiber optic.
