The LC connector is built out of plastic to make it durable and safe, and the connector latches in such a way as to make the connection secure and snap-in, reducing the possibility of accidental disconnection. An LC (Lucent Connector) is a small-form-factor fiber optic connector that uses a 1. 25 mm ceramic ferrule and a secure push-pull latch mechanism. It supports both single-mode and multimode fibers and is especially common in duplex configurations for full-duplex communication (transmit/receive). Once the connector is inserted into the port, it can only be removed with a. The LC connector, short for Lucent Connector, was developed by Lucent Technologies (now part of Nokia) in the 1990s as a next-generation alternative to older SC and ST connectors. By MISHA STOUKLOV, OFP -- In the modern world we are connected like. Like the SC type connector, the LC fiber optic connector is easy to plug in or remove, providing a secure, precisely aligned fit conforming to TIA/EIA 604 standards.
