Ultra dense WDM with agile and flexible DSP add-drop

摘要

A system, e.g. for optical communication, includes an I-Q modulator and a transmission signal processor. The I-Q modulator is configured to modulate a first light source in response to first I and Q modulation signals. The transmission signal processor is configured to receive a data stream including data corresponding to a first data subchannel. The processor maps the data subchannel to an optical transmission subchannel and outputs the first I and Q modulation signals. The I and Q modulation signals modulate the light source to produce an optical transmission signal that includes wavelength components corresponding to the optical transmission subchannel.

1. A system comprising:
a first I-Q modulator configured to modulate a first light source in response to first I and Q modulation signals; a second I-Q modulator configured to modulate a second light source in response to second I and Q modulation signals; a transmission signal processor configured to:
receive a data stream including data corresponding to a first data subchannel;map said first data subchannel to a first optical transmission subchannel; andoutput said first I and Q modulation signals to modulate said first light source to produce an optical transmission signal that includes wavelength components corresponding to said first optical transmission subchannel; and a polarization multiplexer configured to receive outputs of said first and second I-Q modulators and output said optical transmission signal with first and second polarization modes.
