Systems and methods for full duplex coherent optics

A full duplex communication network, comprising:

• an optical transmitter end including a first coherent optics transceiver having a laser source, a first coherent optics transmitter, and a first coherent optics receiver;
• an optical receiver end including a second coherent optics transceiver;
• an optical transport medium operably coupling the first coherent optics transceiver to the second coherent optics transceiver having a second coherent optics transmitter and a second coherent optics receiver;
• and
• wherein the first coherent optics transceiver is configured to simultaneously transmit a first optical signal and receive a second optical signal,
• wherein the second coherent optics transceiver is configured to simultaneously receive the first optical signal from the first coherent optics transceiver and transmit the second optical signal first coherent optics transceiver,
• wherein at least one of the first optical signal and the second optical signal includes at least one coherent optical carrier and at least one non-coherent optical carrier, and
• wherein the first coherent optics transmitter comprises a coherent modulator configured to (i) convert an electrical signal into the at least one coherent optical carrier, and (ii) modulate the at least one coherent optical carrier using the laser source.
