The tail fiber (also known as tail line, pig tail line). One end of it has a connecting head, and the other end is a broken end of a fiber optic cable core, which is welded with other fiber optic cable core to complete the connection. In other words, cut a jumper in half from the center, and you have two pigtails. It is often used in fiber optic terminal boxes to connect optical cables to fiber optic transceivers (couplers, jumpers, etc.).
Classification of pigtails
Like fiber optic jumpers, pigtails are also divided into single-mode pigtails and multi-mode pigtails. They have certain differences in color, wavelength and transmission interval. Generally speaking, the multi-mode pigtail is orange, the operating wavelength is 850nm, and the transmission interval is about 500m; The single-mode pigtail color is yellow, the operating wavelength is 1310m or 1550m, and the transmission interval is longer, about 10-40km. In addition, according to the different number of fiber cores, pigtails can be divided into single-core pigtails, 4-core pigtails, 6-core pigtails, 8-core pigtails, 12-core pigtails, 24-core pigtails, etc., which can be selected according to different needs.
The use of pigtails
One of the first effects of pigtails is cohesion. Fiber and pigtail connection: the bare fiber and fiber pigtail in the optical cable are fused together to form a whole, and the pigtail has a single optical fiber head, which is connected to the optical fiber transceiver, connecting the optical fiber and the twisted pair cable to the information socket. In the process of optical fiber welding, the following main things are commonly used: optical end box, optical fiber transceiver, pigtail, coupler, special wire stripper, optical fiber cutting knife, etc. The commonly used pigtails in the transmission system include SC/PC, FC/PC, LC/PC, E2000/APC, and ST/PC interfaces.
There are five types of pigtails commonly used in transmission systems:
FC-SC type, that is, the general round to square pigtail. The FC connects to the ODF box, and the SC connects to the optical port of the device. This fiber optic connector is used more in the early SBS and Optix equipment.
FC- FC type is commonly known as a round pigtail. Generally used as a jumper between ODF frames.
SC-SC type, commonly known as square to square pigtail, is generally used in the connection of optical plates between devices.
SC-LC type, LC interface commonly known as small square tail fiber, belongs to the clip connector. Now Huawei OSN series equipment, ZTE S series equipment, including the earlier Lucent wave division equipment, are using this fiber optic connector.
LC-LC type is generally used in the internal fiber connection between wavelength division devices, and this application is relatively rare.
After the above content, I believe you have a deeper understanding of pigtail. Anhui Wanchuang Communication supplies a variety of connector types of fiber pigtails, pigtails type, length, number of cores can be customized services. All products comply with IEC, TIA/EIA, NTT and JIS standards, low insertion loss and reflection loss, outstanding interchangeability and durability, and high stability function.
