ABSTRACT:
A single component transceiver device for a linear single fiber optical network which allows both reception and transmission of light information onto a linear data line. One embodiment discloses a light source 10 which would apply modulated light signals, or an unmodulated light carrier, onto an optical medium at the end 12 thereof. This light would reach point 14 along the optical fiber and be detected and/or further modulated by diode 16 and this light information is introduced unidirectionally onto the optical fiber. A second embodiment would include a diode 52 along an optical fiber which would detect and/or radiate light signals bidirectionally along an optical fiber. A proposed light transceiver 90 which could be utilized with the above two embodiments is also disclosed.
