ABSTRACT:
An optical transceiver is coupled to a U-shaped optical bus and to data terminals employing CSMA/CD. The optical transceiver includes a converter for carrying out a conversion between data to and from the data terminals and transmitting packets to be transmitted from and receiving packets to be received by the data terminals via the converter, an optical bus interface for matching the transmitting and receiving packets to the U-shaped optical bus which is used as a transmission line, a common bus which provides a data transfer path between the converter and the data terminals during transmitting and receiving operations, a transmitting packet intermission part for intermitting the transmitting packets in response to a transmission control signal, a receiving packet intermission part for intermitting the receiving packets in response to a reception control signal, and a controller for generating the transmission control signal and the reception control signal based on timings of the transmitting packet and the receiving packet, a relationship between the transmitting packet and a corresponding receiving packet which is looped back from the U-shaped optical bus, and a collision notification. The converter notifies a collision on the common bus based on an impedance of the common bus by supplying the collision notification to the controller.
