Assignee: CABLE TELEVISION LABORATORIES, INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A first coherent optics transceiver for a full duplex (FDX) communication network, comprising:
a first coherent transmitting portion;
a first coherent receiving portion;
a control layer; and
a coherent optics interface including (i) a lineside interface portion, (ii) a clientside interface portion, and (iii) a management interface portion in communication with the control layer separately from the lineside interface portion and the clientside interface portion,
wherein the clientside interface portion is configured for electrical communication within at least one of the first coherent transmitting portion and the first coherent receiving portion,
wherein the lineside interface portion includes a directional element disposed between (i) an optical transport medium operably coupling the first coherent optics transceiver to a second coherent optics transceiver disposed remotely from the first coherent optics transceiver and configured to send and receive phase-modulated coherent optical signals to and from the first coherent optics transceiver, and (ii) the first coherent transmitting portion and the first coherent receiving portion, such that the directional element provides a dual optical communication interface with the first coherent transmitting portion and the first coherent receiving portion, respectively, and a single optical communication interface with the optical transport medium, and
wherein the phase-modulated coherent optical signals are simultaneously transmitted from the first coherent transmitting portion at the same wavelength at which the phase-modulated coherent optical signals are received by the first coherent receiving portion.
