Abstract

State-of-the-art of high-capacity optical modulation formats used in high-speed DWDM transmission systems are presented. Simulations of 320 km transmission of DWDM signal show that DQPSK modulation is superior to CS-RZ (carrier-suppressed return-to-zero) and duobinary phase modulation with respect to signal degradation due to Kerr nonlinearities.

高速DWDM系统的光调制格式

介绍了用于高速DWDM传输系统的高容量光调制格式的最新进展。对DWDM信号320 km传输的仿真表明，DQPSK调制在Kerr非线性引起的信号退化方面优于CS-RZ(载波抑制归零)和二元相位调制。
