Tail optical fiber pigtail is also called the pigtail line, only one end has connecting head, and on the other end is the broken ends of a single core fiber optic, by fusion with other fiber core is connected, often appear in the optical fiber terminal box for connecting cable and fiber optic transceiver (also used coupler, the jump wire).
Divided into multimode and single-mode fiber pigtail pigtail. Multimode pigtail is orange, the wavelength is 850nm, the transmission distance is 500m, for short distance interconnects.
SMF is yellow, there are two kinds of wavelength, 1310nm and 1550nm, the transmission distance of 10km and 40km.
ITU-T International Telecommunication Union Telecommunication Standardization Organization (ITU-T for ITU Telecommunication Standardization Sector), standardized three commonly used fiber: with G.652 specification of optical fiber, in line with the G.653 specification of fiber, in line with the standard G.655 fiber.
