Abstract (en)

[origin: WO0225840A1] A long distance fiber optic transmission system for carrying signals over 2000 kilometers without repeaters or dispersion compensation between a head end (10) and a receiving station (20), with total signal carrying capacity of over 500 billion bits per second and 500 billion Hertz. A bank of unmodulated spectral lines, to be modulated spaced about 5 gigahertz on center are generated and transmitted to a head end (10). The bit rate of incoming signals to be transmitted is detected and if the bit rate is too high it is demultiplexed in time (12). The signals are demultiplexed in time until the bit rate of each signal low enough so that it can go to its receive station without needing repeaters.
