Optical fiber patch cord refers to the optical fiber directly connected to the desktop computer or device to facilitate the connection and management of the device Optical fiber jumper is also divided into single-mode and multi-mode, which are connected to single-mode and multi-mode optical fibers respectively. Jumper is a flexible connecting line without connector between two devices (different from patch cord, which has connector at one end or both ends; Jumper is a cable with optical fiber connectors at both ends, which can be directly connected to the equipment, while the pigtail only has optical fiber connectors at one end, and the other end is used to fuse with the optical fiber).

Optical fiber jumper can be divided into FC, SC, ST, LC, etc. according to the joint shape; According to the grinding method (end face) of the connector core, it can be divided into: PC (plane), UPC (spherical surface), APC (inclined 8-degree surface), etc. (FC/APC connector is generally required for cable TV optical transceiver); According to the type of optical fiber, it can be divided into single mode, 50/125 multimode, 62.5/125 multimode, gigabit, 10 gigabit, etc; According to the diameter of tail cable, it can be divided into: 900 μ m. 2mm, 3mm, etc. The products have good interchangeability, repeatability, reliability and stability. With high echo attenuation, low insertion loss, freely selectable length and excellent temperature stability, it can be used in optical fiber communication system, optical fiber data transmission, LAN, optical fiber sensor and optical fiber.
