Abstract:
1. A grooming apparatus for an optical communication network, comprising: a first photoelectric integration unit comprising a wavelength division demultiplexing unit and a photo-electric conversion unit; an electrical-layer grooming unit directly connected to the photo-electric conversion unit without any intervening components; a first electric-photo conversion unit directly connected to the electrical-layer grooming unit without any intervening components, wherein the first electric-photo conversion unit is configured to receive a plurality of second single-wavelength electrical signals from the electrical-layer grooming unit and perform an electric-photo conversion to generate a plurality of second single-wavelength optical signals; a wavelength division multiplexing unit coupled to the first electric-photo conversion unit, wherein the wavelength division multiplexing unit is configured to multiplex the second single-wavelength optical signals generated from the first electric-photo conversion unit into a second multi-wavelength optical signal and output the second multi-wavelength optical signal; an electrical-layer demultiplexing unit coupled to the photo-electric conversion unit and the electrical-layer grooming unit; and an electrical-layer multiplexing unit coupled to the first electric-photo conversion unit and the electrical-layer grooming unit, wherein the wavelength division demultiplexing unit is configured to demultiplex a received multi-wavelength optical signal into a plurality of single-wavelength optical signals, wherein the photo-electric conversion unit is configured to perform a photo-electric conversion on the single-wavelength optical signals generated from the wavelength division demultiplexing unit and generate a plurality of single-wavelength electrical signals, wherein the electrical-layer grooming unit is configured to groom the single-wavelength electrical signals, wherein the electrical-layer demultiplexing unit is configured to demultiplex the single-wavelength electrical signals generated from the photo-electric conversion unit into a unified mapped container signal, wherein the electrical-layer grooming unit is further configured to receive the unified mapped container signal from the electrical demultiplexing unit, groom the unified mapped container signal and send the groomed unified mapped container signal to the electrical-layer multiplexing unit, and wherein the electrical-layer multiplexing unit is configured to multiplex the groomed unified mapped container signal generated from the electrical-layer grooming unit into the groomed second single-wavelength electrical signals and output the groomed second single-wavelength electrical signals to the first electric-photo conversion unit.
