What are the differences between optical fiber jumpers, pigtails and optical fiber connectors, and where are they used?

Optical fiber jumpers are used for jumpers from equipment to optical fiber wiring links. There is a thick protective layer, which is generally used to connect the optical terminal and the junction box.

The pigtail, also called pigtail, has a connector at one end and a broken end of a fiber core of an optical cable at the other end. It is connected with other fiber cores by welding and often appears in an optical fiber junction box to connect the optical cable and the optical fiber transceiver (couplers and jumpers are also used between them). \

Optical fiber connector is a detachable (movable) connecting device between optical fibers, which accurately connects the two end faces of optical fibers, so that the optical energy output from the transmitting optical fiber can be coupled into the receiving optical fiber to the maximum extent, and the influence of its intervention in the optical link on the system is minimal, which is the basic requirement of optical fiber connector. To some extent, optical fiber connectors also affect the reliability and performance of optical transmission systems.
