The LC connector is a high-performance fiber optic connector for single-mode and multi-mode applications, characterized by low insertion loss. It is one of the most common fiber optic connector types. The design of the LC connector is based on a single-fiber ceramic ferrule with a diameter of 1.25 mm for an optical fiber. Due to its compact design, the LC connector allows for high packing density, making it frequently used for fiber optic switches.
