in this paper, based on the PSA technology, the design is proposed by using orthogonal phase shift, differential quadrature phase shift noise suppression type all- optical regenerator system for signal modulation in multi scale. For system performance test regenerator, the simulation in 40GbPS optical fiber transmission line. Analysis of the characteristics of data and indicators, comprehensive resuhs show that phase regenerator technology can PSA amplitude and phase noise in the signal based on stability significantly inhibited, significantly enhance the signal transmission, reduce the energy loss and distortion, the BER 10-12 40Gbps under the condition of the fiber effective transmission distance up to 2000km or more, is a major signal transmission technology breakthrough.
