Abstract: A method of processing optical signals in a passive optical network includes receiving a first signal in a first optical spectrum, and receiving a second signal in a second optical spectrum. The second optical spectrum is different from the first optical spectrum. The method also includes multiplexing the first and second signals into a first multiplexed signal and outputting the first multiplexed signal. The method also includes receiving a second multiplexed signal, and demultiplexing the second multiplexed signal into a third signal and a fourth signal. The third signal is in the second optical spectrum and the fourth signal is in the first optical spectrum. The method also includes outputting the third and fourth signals.

Abstract: A local area network system that includes a residential gateway in wired communication with a remote service provider and multiple set top boxes in wired communication with the residential gateway. Each set top box includes a network extender having a wired connection to a residential gateway of a local area network, a media player in communication with the network extender, and at least one wireless transceiver in communication with the network extender. The media player includes a computing processor executing instructions to format a signal received from the network extender for use by a media device. Each set top box is configured as an access point for a local area network of the residential gateway.

Abstract: An optical network remote node includes first and second node inputs, each receiving a multiplexed optical signal, and node outputs, each outputting a separate demultiplexed optical signal. The node includes first and second optical power splitters, each having a splitter input connected to one of the node inputs and splitter outputs connected to corresponding node outputs. The node includes an arrayed waveguide grating having first and second grating inputs connected to the first and second node inputs, respectively, and grating outputs connected to the corresponding node outputs. If the received signal at one of the node inputs is time division multiplexed, the corresponding connected optical power splitter broadcasts the received optical signal at the node outputs. If the received signal at one of the node inputs is wavelength division multiplexed, the arrayed waveguide grating demultiplexes the received optical signals in wavelength and outputs the demultiplexed signals at the node outputs.
