An administrator wants to replace a fiber-optic cable.

LC stands for Lucent Connector, which is a type of fiber-optic connector that uses a push-pull mechanism to connect and disconnect the cable. LC connectors are small, compact, and widely used for high-density applications, such as data centers, servers, and networks. LC connectors have a 1.25 mm ferrule that can support both single-mode and multimode fibers.
