LC connector.

Also written LC, Lucent Connector.

What is an LC fibre connector?

LC is a small-form-factor fibre connector with a 1.25 millimetre ferrule, half the size of SC. Two LC connectors clip together as a duplex pair for transmit and receive. Being small, it fits twice as many ports on the same panel, which is why it is the standard connector on modern transceivers.

Defined by IEC 61754-20, published by IEC.
