The difference between cable and covered wire pigtail

Pigtail wire pigtail known, only one end of the connector, the other end is a cable core of breakage, fusion and other fiber optic cable through the core is connected, it often occurs within the fiber optic terminal box, cable and fiber optic transceivers for connection device (also used between the coupler, jumpers, etc.).

Pigtail into multimode and single mode pigtail pigtail. Multimode pigtail orange wavelength of 850nm, the transmission distance of 500m, for a short distance interconnection. Single-mode pigtails yellow, there are two wavelengths, 1310nm and 1550nm, transmission distance of 10km and 40km.Covered wire hanging cable commonly known as indoor wiring cable.

Optical access in the domestic market has shown a good momentum of development in the case, optical fiber access has become a hot field. In the fiber access project, close to the user's house wiring is the most complex aspects of conventional indoor cable bending performance, tensile properties can not meet the FTTH (fiber to the home) house wiring needs. Thus, in 2002, according to market demand by the flames of the development of science and technology covered wire cable, and apply a national patent.

Covered wire cable, mostly single-core, dual-core structure can also be made ​​of four-core structure, leaving 8 shaped cross section, reinforcement in the center of two circles, can be metallic or nonmetallic structures, fiber geometric center of the font in the 8 . War within the fiber optic cable technology covered wire using G.657 small bend radius fiber bend radius of 20mm can be laid for building the pipeline in-line or by Buming home. Covered wire cable can be a unique 8-shaped structure in the shortest time to achieve the scene into a side, now Corning, 3M, manufactured by Fujikura connectors are a variety of on-site with standard-size 2.0mm × 3.1mm adapter cable covered wire and widely used around the world.
