SC connectors support both single-mode and multimode fibers, offering options like simplex, duplex, and various polishing types (UPC and APC) for compatibility across applications. Ensure wavelength compatibility: Match fiber patch cable type to transceiver wavelength (e., 850nm for multimode, 1310nm for single-mode)., OM4 instead of OM3) to better support future network upgrades. They act as the critical link for interconnecting devices like optical switches, servers, and distribution frames. It is mainly used in applications such as optical fiber communication systems, optical fiber access networks, optical fiber data transmission networks, and local area networks.
