ABSTRACT:
The electronic-to-optical multiplexer takes n electronic inputs Xiwhere i=0 to n−1; converts Xiinto optical signals Yieach with a different wavelength; wavelength multiplexes Yi; samples Yiwith an optical frame sync signal having a period of n*p seconds and a pulse width w; wavelength demultiplexes Yi; staggers Yiby i*p seconds; wavelength multiplexes Yi; gates an optical clock signal with Yi; and uses the gated optical clock signal as the optical output.The optical-to-electronic demultiplexer takes n optical sources Zieach with a different wavelength; wavelength multiplexes Zi; gates Ziwith the input of the optical-to-electronic demultiplexer; wavelength demultiplexes Zi; staggers Ziby (n−i)*p seconds; wavelength multiplexes Zi; gates Ziwith the frame sync signal delayed by (n−1)*p seconds; wavelength demultiplexes Zi; detects Ziwith detectors DECTi; and uses the output of DECTias the electronic outputs.
