LC stands for a type of optical connector of which the full name is Lucent Connector. It comes with the name because the LC connector was firstly developed by Lucent Technologies (Alcatel-Lucent for now) for telecommunication applications. It uses a retaining tab mechanism and the connector body resembles the squarish shape of SC connector. Similar to the SC type connector, LC fiber optic connector is easy to plug in or remove, providing a secure, precisely aligned fit conforming to TIA/EIA 604 standards. Until now, it is still one of the most popular fiber optic connectors in the fiber optic market.
