The LC connector is a high-performance fiber optic connector for singlemode and multimode applications, characterized by low insertion loss. It is one of the most common types of fiber optic connectors. The design of the LC connector is based on a single-fiber ceramic ferrule with a diameter of 1.25 mm for a fiber optic cable. Due to its compact design, the LC connector allows for a high packing density, making it frequently used in fiber optic switches. SC connectors are standard connectors for fiber optic cabling. They feature automatic locking and twist protection. Their use is recommended for installations of computer networks using fiber optic technology. The connector is suitable for both singlemode and multimode fibers, allowing for simplex, duplex, and multi-fiber connections.
