Systems and methods of wavelength division multiplex passive optical networking

A method comprising

• receiving a data signal;
• modulating the data signal with an optical line termination transmitter laser at a particular wavelength;
• transmitting the modulated signal to a wavelength router for transmission on a single fiber optical distribution network;
• and
• transmitting a part-time control channel in the C band (1530 nm-1565 nm) and the L band (1565 nm-1625 nm).

A system comprising:

• an optical line termination (OLT) transmitter laser of a plurality of OLT transmitter lasers configured to transmit at a particular wavelength and to transmit a part-time control channel in the C band (1530 nm-1565 nm) and the L band (156 nm-1625 nm);
• a wavelength router configured to couple a downstream optical signal from the OLT transmitter laser onto a single fiber optical distribution network for reception by a passive optical power splitter, the wavelength router further configured to receive an upstream optical signal from the single fiber optical distribution network and route the upstream optical signal to an appropriate receiver;
• a plurality of optical network units (ONUs) configured to receive downstream optical signals and transmit upstream optical signals;
• and
• a passive optical power splitter configured to route the downstream optical signal to a particular ONU of the plurality of ONUs based on the received wavelength.
