| 摘 要： | 分析了DPSK调制格式的产生方式和频域特性,在分别考虑色散、PMD和非线性效应的情况下,通过求解非线性薛定谔方程,仿真了NRZ-DPSK,33%RZ-DPSK,50%RZ-DPSK和CSRZ-DPSK调制格式在40 Gbit/s单信道中的传输特性.仿真结果表明,在单独考虑色散和PMD的情况下,33%RZ-DPSK调制格式特性较好,在综合考虑色散、PMD和非线性效应情况下,CSRZ-DPSK调制格式特性更好.

| Abstract: | The generation and frequency domain characteristic of NRZ,33%RZ,50%RZ and CSRZ in DPSK modulation formats are analyzed.Considering PMD,CD and the nonlinear separately,DPSK modulation formats are investigated by the coupled nonlinear Schrodinger equation solved by means of split-step Fourier transform method in 40 Gbit/s single channel.Simulation results indicate that 33% RZ-DPSK is better than the other DPSK modulation formats under considering CD and PMD separately,but CSRZ-DPSK is the best when CD,PMD and... |
