The invention discloses an optical probability shaping method based on diamond modulation and symbol level partial marking mode. Under the condition of satisfying minimum Euclidean distance, the spatial advantage of the constellation map is achieved, and the diamond QAM constellation map is proposed. At the same time, by combining with the proposed symbol-level probability shaping method, the distribution probability of low energy points of the input signal is improved and the transmission performance of the system is improved by increasing redundancy.
