新型APol-CSRZ-FSK调制格式的研究

摘要

结合了偏振调制、载波抑制归零码和频移键控的优点,提出了一种交替偏振频移键控载波抑制归零码(APol-CSRZ-FSK)调制技术,它可运用于40 Gbit/s光传输系统.利用APol-CSRZ-FSK调制技术实现了40 Gbit/s的长距离光传输的仿真,结果证明APol-CSRZ-FSK具有良好的传输性能,并且是未来WDM-PON或光标记交换网络的候选码型之一.%A modulation format "APol-CSRZ-FSK" integrating altemating advantages of polarization modulation,carrier suppression return-to-zero and frequency shift keying,which can be used in 40 Gbit/s optical transmission system is proposed in this paper.Appling APol-CSRZ-FSK modulation format to carry out the simulation of 40 Gbit/s long-haul optical transmission proves its excellent transmission performance.APol-CSRZ-FSK modulation format will be a candidate of the future WDM-PON or optical label switching systems.
