摘要
将抑制载波归零(CSRZ)码与先进的多进制调制技术结合应用于40Gb/s的光通信系统中,分析了其抗色散和抗非线性能力。仿真结果表明,随着进制的提高,信号的抗色散能力增强,抗非线性性能变差。在此基础上,还研究了采用3种不同的色散补偿方式时,多进制相位调制格式的Q值随入纤光功率变化的变化情况。
The CSRZ code combined with advanced multi-band modulation technique was applied to 40Gb/s in the optical communication system, analyzes its dispersion and non-linear resistance. The simulation results show that with the increase of base, the signal enhanced ability to resist dispersion, nonlinear resistance is poor. Based on this, we has also studied multi-band phase modulation formats of Q value along with the change of the fiber optical power under three different dispersion compensation mode.
