Fiber optic transmission is that an electrical is converted into light (light source) which is transmitted through along the optical fiber into the receiver where the light signal is converted into electrical signal (light detector). Fiber optic transmission has many advantages over other communication system. Major limiting characteristic of in an optical fiber communication is the loss of the optical signal as it goes through the fiber. The performance if the optical fiber is related the end to end loss in the passive optical fiber cable between the transmitter and receiver. The passive fiber optic link may include fiber optic cable, fiber optic connectors, fiber optic adapters, fiber optic splices and fiber optic “hardware” (housings and connector panels).
