(Optical fiber knowledge MM=Multicmodefiber (multimode fiber)?? Core diameter is 50μm (transmission distance 550m) or 62.5μm (transmission distance 330m)?? Appearance is orange?? The propagation distance is relatively short: 330--500m?? SM=Singlemodefiber (Single-mode fiber)?? Core diameter is 9μm?? Appearance is yellow?? Propagation distance is longer: 50km-100km SC connector is a standard square connector, using engineering plastics, which has the advantages of high temperature resistance and not easy to oxidize. The optical interface on the transmission equipment side generally uses the SC connector. The LC connector is similar in shape to the SC connector, which is smaller than the SC connector. The FC connector is a metal connector, which is generally used on the ODF side. The metal connector can be plugged more frequently than the plastic connector. Provides good protection to the fiber core, but it is rotated, which is easy to scratch the fiber core. ST connector has a tenon to avoid damage to the connector, similar to the BNC connector memory method: ??SC=SquareConnector??LC=LittleConnector?? ST=StabandTwist…)
