BIDIRECTIONAL OPTICAL TRANSCEIVER BY MULTI CHANNEL

摘要

A bidirectional optical transceiver of multi channel type is provided to facilitate alignment of optical axes and to transmit and to receive downward and upward optical signals through plural vertical surface light emitting or receiving optical elements. A bidirectional optical transceiver(100) of multi channel type is composed of an optical fiber(110) for transmitting downward optical signals and receiving upward optical signals through the optical transceiver; a plurality of vertical surface light receiving sources(131,132,133,134) for generating the downward optical signals; a plurality of vertical surface light receiving detectors(141,142,143,144) for receiving the upward optical signals; and an optical coupler(120) for outputting the downward optical signals to the optical fiber and outputting the upward optical signals received through the optical fiber, to each vertical surface light receiving detector.
