1. be used in the light modulating method in the optical communication system of the noisy light source of tool in low frequency region, comprise:

  • Transmitter side by the Data Modulation of the noisy described light source of tool in from low frequency region be not there is electric frequency spectrum in low frequency region modulation format to transmit modulated data;

    And from modulated data, remove low-frequency noise recipient and do not affect transmission data, thus improve the performance of described optical communication system, wherein said in low frequency region the noisy light source of tool be by injecting the wavelength locking fabry-Perot laser diode that realizes of wideband light source from outside, the wideband light source injected from outside is the wideband light source using fabry-Perot laser diode to inject mutually.
