Claim 2:
3. The optical signal processing method of claim 1, wherein
the OSNR value includes an OSNR tolerance value of the optical receiving unit, an OSNR cost of an optical channel, and an OSNR redundancy of the OTN system,
wherein the preset threshold is acquired through the following formula: Y0=k1X1+k2X2+k3X3+Δ;
wherein Y0 is the preset threshold, X1 is the OSNR tolerance value, X2 is the OSNR cost, X3 is the OSNR redundancy, k1 k2 and k3 are preset check coefficients, and Δ is a preset check offset.
