The research of the CS-RZ format’s performance in high-speed system
摘要
文章介绍了载波抑制归零码(CS RZ)的产生机制及其优良的传输性能
并采用计算机仿真比较了CS RZ、非归零(NRZ)和归零(RZ)
这三种码在40Gbit/s速率下的传输性能.CS RZ码抗自相位调制(SPM)比较好
而且有高的色散容限.从色散容限和SPM容限的角度来说
CS RZ码是一种最好的调制格式.
Abstract
This paper introduces the production mechanism of carrier-suppressed return-to-zero(CS-RZ) format and its good transmission performance
and also compares the transmission performance of CS-RZ with RZ and NRZ formats at 40 Gbit/s system through computer simulation. CS-RZ format is more effective than other formats in terms of against SPM
and it has high dispersion tolerance. It is actually the best format in terms of tolerance of dispersion and SPM.
