SC connectors are standard connectors for fiber optic cabling. They feature an automatic locking mechanism and a twist protection. Their use is recommended for new installations of computer networks utilizing fiber optic technology. The connector is suitable for single-mode and multi-mode fibers. It can establish simplex, duplex, and multi-fiber connections. The LC connector is a high-performance fiber optic connector for both single-mode and multi-mode applications, distinguished by its 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.
