Claim 0:
1. An optical signal processing method, applied to a control unit, comprising:
acquiring an optical signal noise ratio (OSNR) value from an optical receiving unit;
acquiring a spectrum shaping adjustment parameter according to the OSNR value; and
sending the spectrum shaping adjustment parameter to an optical transmission unit to adjust a filtering parameter of a shaping filter of the optical transmission unit, so that the optical transmission unit adjusts a spectrum waveform of an optical signal by utilizing the shaping filter after adjustments;
wherein the acquiring the spectrum shaping adjustment parameter according to the OSNR value comprises:
in response to that the OSNR value is less than a preset threshold, acquiring an optical signal modulation mode of an optical transport network (OTN) system; and
acquiring the spectrum shaping adjustment parameter from a preset lookup table according to the optical signal modulation mode and the OSNR value.
