description The invention discloses an adjustable all-optical signal format conversion assembly, device and conversion method, relates to the field of communication systems, and solves the problems that in the prior art, a photoelectric-optical conversion mode is adopted for 8QAM format conversion, signal transmission time delay is increased, high-speed large-capacity transmission of data traffic is not facilitated, and the conversion efficiency is high. A coupler, a high-nonlinearity optical fiber, a phase shifter and an attenuator are used for forming a nonlinear optical loop mirror, the nonlinear optical loop mirror is used for adjusting the amplitude state of an 8QAM signal, parameters of all assemblies in the nonlinear optical loop mirror are set, and the 8PSK or rectangular 8QAM signal is obtained. Therefore, network attacks on an electric layer can be effectively prevented, the processing of all-optical format conversion on signals of different modulation formats avoids a photoelectric-optical conversion mode, sig
