基于PSA技术,设计提出了多进位制中可采用正交相移、差分正交相移进行信号调制的抑制噪声型全光再生器系统。为检验再生器的系统性能,将其仿真模拟于40Gb PS光纤传输线路中。分析信号特点和数据指标,综合结果得出:基于PSA技术的相位再生器可显著抑制信号中的幅度及相位噪声,大幅提升信号传输的稳定性,并降低了能量损耗和失真,使BER为10-12条件下40Gbps光纤的有效传输距离提升至2000km以上。
Based on the PSA technology, a noise-suppressed all-optical regenerator system based on quadrature phase shift and differential quadrature phase shift in multi-carry system is proposed. To test the regenerator’s system performance, it was emulated in a 40Gb PS optical fiber transmission line. The signal characteristics and data indexes are analyzed. The results show that the phase regenerator based on PSA technology can significantly reduce the amplitude and phase noise in the signal, greatly improve the stability of signal transmission and reduce the energy loss and distortion so that the BER is 10 -12 conditions, the effective transmission distance of 40Gbps optical fiber is increased to more than 2000km.
