Abstract
A cross-connecting optical translator array that electronically switches opto-electronically converted signals received from optical transmission systems and that uses an optical transmitter to generate optical signals having the required wavelength for succeeding optical transmission systems. The cross-connecting optical translator array includes optical converters that are coupled to an input side of an electronic space switch fabric. Optical transmitters are coupled to an output side of the electronic space switch fabric. The optical transmitters are selectable to provide optical interface capability with the various wavelength optical fibers used in optical transmission systems. The combination of the optical converters and the optical transmitters operationally provide an optical translator that receive optical signals at a first wavelength and can transmit optical signals at a second wavelength. The operating speed of the array is compatible with that of the optical transmission systems. A multiple layer architecture can be used to accommodate increasingly greater optical transmission speeds by decreasing the input bit rate into multiple subrate streams and by parallel proces…
