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 high packing density, making it frequently used for fiber optic switches. Multimode fibers have a larger core diameter than singlemode fibers, resulting in more light refraction and therefore greater attenuation. They are particularly suitable for shorter transmission distances. The OM designation for a fiber optic cable defines the quality class of a multimode fiber optic cable. The classification distinguishes four classes (OM1 to OM4), based on the level of optical attenuation and the possible transmission rate and distance. For the OM2 class, a bandwidth-length product of 500 MHz x km is specified at 850 nm.
