Abstract
An optical fiber communication apparatus includes a main optical fiber having dispersive characteristics; a semiconductor laser diode for outputting an optical signal transmitted through the main optical fiber; a photodiode for receiving the optical signal output from the main optical fiber and a dispersion canceling short distance optical fiber having a total dispersion approximately the same as and in a reverse phase from the total dispersion of the main optical fiber at the wavelength of the optical signal, correcting the total dispersion produced by the main optical fiber and located at one of the input and output end of the main optical fiber. An optical signal traveling through the signal transmission line becomes a reformed rectangular waveform at the output end so that reading errors can be eliminated, resulting in highly reliable communication.
