LC(F)-SC(M) DX Hybrid Adaptor

LC stands for Lucent Connector. The LC is a small form-factor Fiber optic connector. The LC Connector uses a 1.25 mm ferrule, half the size of the SC. Otherwise; it is a standard ceramic Ferrule connector. The LC has good performance and is highly favored for single mode. APC polish is with an angle for 8 degrees in the ferrule.

SC stands for Subscriber Connector- a general purpose push/pull style Connector developed by NTT. SC has an advantage in keyed duplexibility to support send/receive channels.
