LC To SC UPC Duplex

Relative to LC To SC UPC Duplex,Optical fiber jumpers (also known as optical fiber connectors), that is, optical fiber connectors that are connected to optical modules, are also available in many types, and they cannot be used mutually. The SFP module is connected to the LC fiber optic connector, and the GBIC is connected to the SC fiber optic connector. The following is a detailed description of several commonly used optical fiber connectors in network engineering:
â‘ FC-type fiber jumper: The external strengthening method is a metal sleeve, and the fastening method is a turnbuckle. Generally used on the ODF side (most used on the distribution frame)
â‘¡SC type optical fiber jumper: the connector that connects to the GBIC optical module, its shell is rectangular, and the fastening method is a plug-in latch type, without rotation. (Most used on router switches)
â‘¢ST type optical fiber jumper: commonly used in optical fiber distribution frame, the shell is round, and the fastening method is turnbuckle. (For 10Base-F connection, the connector is usually ST type. Commonly used in optical fiber distribution frame)
â‘£LC-type optical fiber jumper: the connector for connecting the SFP module, which is made by the easy-to-operate modular jack (RJ) latch mechanism. (Router commonly used)
