Wdm passive optical network with parallel signal detection for video and data delivery

A wavelength division multiplexed passive optical network architecture, comprising:

• an optical line terminal configured to transmit first and second wavelength division multiplexed content over an optical link and receive signals from the optical link;
• a remote node coupled to the optical link, the remote node comprising:
• a band coupler configured to demultiplex first and second wavelength division multiplexed content transmitted from the optical line terminal into a first band signal and a second band signal;
• an arrayed wavelength grating configured to receive the first band signal and to further demultiplex the first band signal into different wavelengths to provide a plurality of wavelength signals;
• and
• an optical splitter configured to split the second band signal into sub-signals and multiplex the sub-signals with each of the wavelength signals such that the first and second wavelength division multiplexed content is provided on a single wavelength;
• and
• a plurality of optical network units, each configured to receive both the first and second wavelength division multiplexed content on the single wavelength where different wavelengths are sent to each of the optical network units.

A method for delivering data and video services over a wavelength division multiplexed passive optical network, comprising:

• wavelength division multiplexing at least one data channel and at least one video channel for transmission over an optical link using subcarrier modulation to provide wavelength division multiplexed content;
• at a remote location, demultiplexing the wavelength division multiplexed content received from the optical link into a first band signal and a second band signal;
• demultiplexing the first band signal into different wavelengths to provide a plurality of wavelength signals;
• splitting the second band signal into sub-signals;
• and
• multiplexing the sub-signals with each of the wavelength signals such that the wavelength division multiplexed content including data and video content are provided on a single wavelength to a user.
