While a conventional signal in a copper cable is subject to electrical interference, optical cables operate flawlessly even under the most challenging conditions. Additionally, optical fibers do not affect electronics. The low attenuation of optical cables allows for long distances to be covered. 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 using fiber optic technology. The connector is suitable for single-mode and multi-mode fibers. It can be used to create simplex, duplex, and multi-fiber connections. The LC connector is a high-performance fiber optic connector for single-mode and multi-mode applications, boasting an insertion loss of only 0.1 dB and a return loss of 55 dB. The design of the LC connector is based on a single-fiber ceramic ferrule with a diameter of 1.25 mm for a light guide.
