Frequency division multiple access optical subcarriers

Abstract

Transmitters and receivers, including a transmitter, comprising: a laser operable to output light; a processor operable to receive data and provide a plurality of electrical signals based on the data; and a modulator operable to modulate the light to provide a plurality of optical subcarriers, spectrally adjacent optical subcarriers of the plurality of optical subcarriers being spaced from one another by a guard band, a first one of the plurality of subcarriers carrying first control information, and a second one of the plurality of subcarriers carrying second control information, the first control information being indicative of a first parameter associated with a first node remote from the transmitter and the second control information being indicative of a second parameter associated with a second node remote from the transmitter.
