Its job is to hold the fiber in precise alignment so light transfers across the mating interface with low loss. SC is still one of the most useful connector formats to understand if you work in MRO, OEM machine building, or plant networking. SC interface: SC interface is widely used in industrial switches, with a rectangular appearance and a plug-in pin and latch fastening method, making it easy to operate. Most SFP fiber optic modules use LC connectors, while SC connectors are mainly found in legacy networks and MPO/MTP connectors are used for high-density cabling rather than directly on standard SFP modules. This connector landscape reflects how modern SFP deployments prioritize port density and. If you are upgrading a network switch or deploying fiber to the home (FTTH), you will inevitably face the connector choice: LC vs SC.
