Several Optical Fiber interfaces (ST, SC, LC, FC)

Several Optical Fiber interfaces (ST, SC, LC, FC)
I have never been very clear about Several Interfaces of optical fibers. I have seen real images on the Internet and shared them with you. The optical fiber is sometimes annoying and summarizes several commonly used optical fiber connectors.


The above figure shows LC to LC. LC is the SFP commonly used by routers and the line head inserted by mini GBIC.

FC to SC, FC End Plug fiber step frame, SC end is catalyst or other or above GBIC plug cable.

ST to FC. For 10Base-F connections, the connector is usually of the ST type, and the FC on the other end is connected to the fiber step frame.

The two ends of SC to SC are GBIC ..

SC to LC, one GBIC and the other MINI-GBIC.
