Device for transmitting and receiving optical data on the same optical transmission line

摘要

An optical device for the simultaneous transmission and reception of optical data on the same optical waveguide. A transmission and receiving means at each end of the fiber optic cable permits simultaneous transmission. Each transmit/receive means comprises a pedestal supporting an emitter and photodetector. The emitter is mounted centrally of the inner surface of the pedestal at the focal point of a circular ellipsoidal reflector. The photodetector is also mounted centrally of the inner surface of the pedestal and placed forward of the emitter. In this manner the emitters and photodetectors at each end of the fiber optic cable can transmit and receive simultaneously or in sequence on the same optical waveguide.
