Abstract:
1. A high speed optical routing apparatus having an optical router for routing optical data, comprising: means for receiving input optical signals through a plurality of input puts and an add port, wherein said input optical signals having a plurality of data wavelengths and at least a first header wavelength containing header information on respective wavelengths of said plurality of data wavelengths; an extraction unit for extracting said first header wavelength from the input optical signals; a demultiplexer for demultiplexing the plurality of data wavelengths according to wavelengths of the optical signals; a converter/reconverter unit for converting the demultiplexed data wavelengths into divided electrical signals, and then for reconverting the divided electrical signals into reconverted optical signals; and a switch for switching the reconverted optical signals according to the header information, subsequent to their reconversion to electrical signals, wherein a capacity of the apparatus is substantially in Tb/s (terra-bytes) and said apparatus is arranged in a monolithic structure, without requiring a plurality of routers and at least one tunable wavelength converters (TWC).
