1. An apparatus for a coherent optical communication access network having a local transceiver in operable communication with a remote transceiver over an optical transport medium, the apparatus comprising:
an electrical interface unit configured to (i) receive a plurality of outgoing electrical data signals from a media access control (MAC) layer of the local transceiver, and (ii) transmit a plurality of incoming electrical data signals to the MAC layer of the local transceiver;
a control interface unit in operable communication with the MAC layer of the local transceiver separate from the plurality of outgoing and incoming electrical data signals;
an optical interface unit disposed within a physical layer (PHY) of the apparatus, and in operable communication with a control signal from the control interface unit, the optical interface unit configured to (i) transmit an outgoing optical data signal to the optical transport medium based on the control signal and the received plurality of outgoing electrical data signals, and (ii) receive an incoming optical data signal from the optical transport medium.
