1. A transmission link for transmitting an optical fiber communication signal for transmission over an optical fiber, the optical transmission link comprising:

  • a symbolizer for receiving an input data signal comprising a series of pulses, each pulse having one of two distinct pulse levels, wherein the symbolizer is operative to convert n pulses from the input data sign into an error resistant n-bit output word, and further operative to generate an output symbol representing one of 2n distinct values; and

    an optical source for transmitting an output signal comprising a series of the optical symbols over the optical fiber, each optical symbol having one of 2n intensity levels; and

    wherein the symbolizer is further operative to modify a signal property of each optical symbol, according to a signal property of a preceding optical symbol and a signal property of a succeeding optical symbol.
