Summary:The invention relates to the technical field of optical communication, in particular to a method and a system for measuring return loss of an optical communication system. According to the scheme, the mode field of the to-be-measured piece at the corresponding position in the optical communication system is described according to the deflection angle and the gap of the to-be-measured piece in the optical communication system, then the coupling efficiency of the optical coupler in the return loss measurement system is calculated according to the mode field, and the optical coupler is selected according to the coupling efficiency. Then the reflectivity of the to-be-detected piece is calculated according to the coupling parameter, the coupling efficiency, the optical power emitted by the light source and the optical power reflected to the detector by the to-be-detected piece, and finally the return loss value of the to-be-detected piece in the optical communication system is calculated according to the reflectiv
