LC Field Fiber Optic Circular Connectors

Amphenol Fiber Systems International (FSI) LC Field Fiber Optic Circular Connectors transform LC patch cords into harsh environment connectors. The patented RJStop® system turns a standard LC patch cord into a metallic plug, protecting it from shock, dust, and fluids. The vibration-proof connectors provide solid reliable connectivity through a wide range of harsh environments. The series offers 0.5dB typical insertion loss in multimode and single mode and is compatible with all qualified MILDTL-38999, Series III connectors. Amphenol FSI LC Field Fiber Optic Circular Connectors are railways, base stations, navy, and military communications.
