Fiber Optics The technique of transmitting information through flexible glass or plastic fibers using lightwaves. The 3 components of a basic fiber optic system Transmitter, physical plant, receiver The physical plant component of a basic fiber optic system consist of: The cable, connectors, splices, panel, and closures Part of the receiver converts the optical signal back into an electrical signal. The detector a positive intrinsic negative (PIN) photodiode or an avalanche photodiode (APD). Two types of light in the fiber optic equipment. Light Emitting Diode (LED) and Light Amplification by Stimulated Emissions of Radiation.
