Which is better for optical modules LC or SC
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. LC, SC, MPO, and MTP are the four primary fiber connector types used in enterprise networks. This choice becomes even more important when using BiDi (single-fiber bidirectional) modules. The connector type can affect how much physical space you use, how easy the system is to maintain.
