Abstract
A communications device of the present invention includes a single optical transceiver that carries out bi-directional communications using a single optical fiber, and a double optical transceiver that carries out bi-directional communications using two optical fibers, the single optical transceiver and the double optical transceiver being connected to a common communications control IC. This reduces both size and cost of the device, in addition to reducing the amount of delay that is caused in signal conversion between the single optical transceiver and the double optical transceiver.
