Abstract
An object is to provide an optical transceiver in which two single-core bidirectional optical communication devices are mounted on a single substrate. A first substrate includes an electric connector connected to an optical transmission apparatus, and a signal processing circuit processing electric signals that are input to and output from first and second optical transceiver modules. Components outputting a control signal to the signal processing circuit is mountd on a second substrate. A flexible printed circuit connects the first substrate to the first and second optical transceiver modules.
