Abstract:
An apparatus for communicating data through a plurality of information channels each being associated with its own wavelength, said apparatus comprising:a plurality of modulators each being associated with its own wavelength; an optical multiplexer operationally coupled to said plurality of modulators, said optical multiplexer receiving a plurality of input optical signals, each input optical signal from the plurality of input optical signals being received from its own modulator from the plurality of modulators, each input optical signal from the plurality of input optical signals having its own dispersion substantially equal to a dispersion of each remaining input optical signal from the plurality of input optical signals; and a transmission optical fiber operationally coupled to said optical multiplexer and including a plurality of dispersion-compensation fiber segments, said optical multiplexer being disposed between said plurality of modulators and said transmission optical fiber, said plurality of dispersion-compensation fiber segments having an end-to-end dispersion slope substantially equal to zero.
