Fiber optic patch cords are characterized by:
Low insertion loss
High return loss
Good repeatability
Good interchange
Excellent environmental adaptability
A fiber optic patch cord is constructed from a core with a high refractive index, surrounded by a coating with a low refractive index that is surrounded by a protective jacket. Transparency of the core permits transmission of optic signals with little loss over great distances. The coating's low refractive index reflects light back into the core, minimizing signal loss. The protective jacket minimizes physical damage to the core and coating.
Patch cables are used for connections to CATV (Cable Television), telecommunication networks, computer fiber networks and fiber test equipment. Applications include communication rooms, FTTH (Fiber to The Home), LAN (Local Area Network), FOS (fiber optic sensor), Fiber Optic Communication System, Optical fiber connected and transmitted equipment, Defense combat readiness, etc.
