ABSTRACT:
An optical transceiver module is disclosed, particularly for connection to a bidirectional optical-waveguide communications network. It contains an optical transmitter (S), an optical receiver (E), and wavelength-selective means (K, C) which prevent any optical feedback to the optical transmitter (S) and the optical receiver (E) and guide the light to be received exclusively to the optical receiver (E). Such means are, for example, wave-length-selective couplers (C, K) implemented as fiber-optic couplers or as one or more integrated optical devices.
