Function of jumper wire connection to the fiber optic tray
Optical fiber jumper (also known as optical fiber connector) means that both ends of the optical cable are equipped with connector plugs to realize the active connection of the optical path; one end with a plug is called a pigtail. FC Connector: use a metal sleeve for external reinforcement, fastened with a screw fastener. The SFP module is connected to an LC fiber optic connector, while the GBIC is connected to an SC fiber. Fiber optic splicing refers to optical communication, which involves connecting one or more optical fibers end to end. In the optical communication system, this can be done mainly in two ways: through fusion splicing and mechanical splicing. In plain terms, an ODF is the enclosure where incoming fiber cables are routed, spliced, terminated and cross-connected to the active equipment or jumper/patchcords that feed the rest of a network.
