The tail fiber (also known as the tail fiber, pigtail line). It has an adapter at one end and a broken end of a fiber optic cable core at the other end, which is connected to other fiber optic cable cores by welding. In other words, a jumper is cut into two sections from the center to become two pigtails. It often appears in fiber optic terminal boxes and is used to connect fiber optic cables to fiber optic transceivers (couplers, jumpers, etc. are also used between them).
Classification of pigtail
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 multimode pigtail is orange, the operating wavelength is 850nm, and the transmission interval is about 500m. The single mode pigtail is yellow, and the operating wavelength is 1310m or 1550m. It can transmit longer intervals, about 10-40km. . In addition, depending on the 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. Choose according to different needs.
Application of pigtail
One of the most important effects of pigtails is connection. The optical fiber and pigtail are connected, and the bare fiber and the fiber pigtail in the optical cable are fused together into a whole, and the pigtail has an independent fiber head, which is connected to the optical fiber transceiver to connect the optical fiber and the twisted pair. To the information outlet. In the process of optical fiber splicing, the following first things are commonly used: optical end boxes, fiber optic transceivers, pigtails, couplers, special wire strippers, fiber cutters, etc. The pigtails commonly used in the transmission system are SC / PC, FC / PC, LC / PC, E2000 / APC, and ST / PC.
There are five types of pigtails commonly used in transmission systems:
FC-SC type, also known as the round 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 earlier SBS and Optix equipment.
FC-FC type, commonly known as round pigtail. Generally used as a fiber jumper between ODF racks.
SC-SC type, commonly known as square-to-square pigtail, is generally used for the connection of optical boards between devices.
SC-LC type, LC interface is commonly known as small square head pigtail, which is attributed to the snap-in connector. Now Huawei’s OSN series equipment, ZTE’s S series equipment, including pre-Lucent’s WDM equipment, all use this kind of optical fiber connector.
LC-LC type is generally used in the internal fiber connection between WDM equipment. This application is relatively rare.
After the above, I believe we have a deeper understanding of pigtails. Easy Sky Optical provides optical fiber pigtails with various connector types. The pigtail type, length, and number of cores can be customized. All products comply with IEC, TIA / EIA, NTT and JIS standards, low insertion loss and reflection loss, excellent interchangeability and durability, and high stability.
