Q: Can I plug an SC cable into an LC SFP port? A: No. You must use a fiber patch cord with LC on one end (to plug into the SFP) and SC on the other end (to plug into your fiber patch panel). Q: Why are SC connectors preferred for FTTH?Among the most common connectors are LC and SC types, each designed for specific needs and environments. What Are LC and SC Fiber Connectors?Small Form-factor Pluggable (SFP) modules, which connect network devices like switches, routers, and servers to fiber optic cable connector, have become a standard component in modern networks. This choice becomes even more important when using BiDi (single-fiber bidirectional) modules. 5 mm ferrule with a push-pull locking system, which suits.
