Abstract
An optical communication device, such as a transceiver, can send outgoing information over an optical link and receive incoming information via the link. The link, for example an optical fiber, can simultaneously transmit outgoing light carrying outgoing information and incoming light carrying incoming information. The communication device can comprise a detector outputting electrical signals in response to receiving optical signals, effectively converting signals from the optical domain to the electrical domain. The detector can receive a mixture of the incoming and the outgoing light, thereby producing an electrical signal containing imprints of both the incoming data and the outgoing data. The communication device can process the electrical signal to differentiate between the incoming data and the outgoing data. Knowing the outgoing data, the optical communication device can subtract from the electrical signal the portion of the signal associated with the outgoing light, thereby revealing the incoming data.
