Optical fiber jumpers refer to optical fibers that are directly connected to desktop computers or equipment to facilitate the connection and management of equipment. Optical fiber jumpers are also divided into single-mode and multi-mode, which are connected to single-mode and multi-mode optical fibers respectively. A jumper is an active connection wire without a connector between two devices (different from: a patch cord has a connector at one or both ends; a jumper is both ends of a cable All have fiber optic connectors, which can be directly connected to the equipment, while the pigtail has only one end of the fiber optic connector, and the other end is used for splicing with the fiber).

According to the shape of the connector, the fiber jumper can be divided into: FC, SC, ST, LC, etc.; according to the grinding method (end face) of the ferrule, it can be divided into: PC (plane), UPC (spherical surface), APC (8-degree oblique surface) ), etc. (Cable TV optical transceivers generally require FC/APC connectors); according to the type of optical fiber, it can be divided into single mode, 50/125 multimode, 62.5/125 multimode, gigabit, 10G, etc.; according to the diameter of the pigtail cable, it can be divided into For: 900μm, 2mm, 3mm, etc. The product has good interchangeability, repeatability, reliability and stability. High return attenuation, low insertion loss, freely selectable length, excellent temperature stability, can be applied to optical fiber communication systems, optical fiber data transmission, LAN, optical fiber sensors and optical fibers.

What are the differences between fiber jumpers, pigtails and fiber optic connectors?

Fiber optic patch cords are used to make patch cords from equipment to fiber optic cabling links. There is a thicker protective layer, which is generally used for the connection between the optical transceiver and the terminal box.

Pigtail, also known as pigtail, has only one end with a connector, and the other end is a broken end of a fiber optic cable core. It is connected to other fiber optic cable cores by welding. It often appears in fiber optic terminal boxes. (couplers, jumpers, etc. are also used between them).

Optical fiber connector is a device for detachable (active) connection between optical fiber and optical fiber. It precisely butts the two end faces of optical fiber, so that the light energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. And minimize the impact on the system due to its involvement in the optical link, which is the basic requirement of fiber optic connectors. To a certain extent, fiber optic connectors also affect the reliability and performance of optical transmission systems.
