1. optical transmission system comprises:

  • Transmitter, this transmitter is when sending light signal, with positive linear frequency modulation parameter alpha value this light signal is carried out pre-linear frequency modulation, this transmitter comprises the dispersion compensator with negative dispersion characteristic, this transmitter produces the signal with the pulse duration that narrows down, and this pulse duration narrows down according to chromatic dispersion compensation quantity and linear frequency modulation parameter value;

    A plurality of image intensifers;

    Receiver, all uses as optics with this receiver this transmitter, image intensifer;

    And transmission path, each path is connecting two opticses, makes each transmission path all in the front of an optics,Each image intensifer and this receiver all comprise dispersion compensator respectively, and each dispersion compensator all has and the corresponding chromatic dispersion compensation quantity of path-length in front.
