REFLEKTIONSSENDER FUER EIN BIDIREKTIONALES LWL-KOMMUNIKATIONSSYSTEM.

摘要

The reflection transmitter is formed through a bisected controllable directional coupler (MOR) connected at its one input/output (AI) to the optical fibre (LWL). Its two strip waveguides (SLI, SLII) are terminated by a part-transparent mirror (S) and its control electrodes (E,O) are fed with the transmit signal. Pref. behind the mirror (S) there is an optoelectronic converter (o/e) which is fed from the two striplines (SLI, SLII) with the received light signal. The outer input/output (AII) may be terminated by a light absorber. The directional coupler electrodes (E,O) fed with the transmit signal may be sectionally arranged and oppositely poled.
