ABSTRACT:
An integrated optical transceiver includes an optical receiver that produces a first electrical signal at a reception electrical interface in response to a first optical signal, an optical transmitter that emits a second optical signal in response to a second electrical signal received at a transmission electrical interface, a first optical branching device that receives the first optical signal at an reception optical interface and to direct at least a portion of the first optical signal to the optical receiver, and a second optical branching device that directs the second optical signal to an transmission optical interface. The first optical branching device directs at least a portion of the first optical signal to the second optical branching device. The second optical branching device directs the portion of the first optical signal received from the first optical branching device to the transmission optical interface.
