【摘要】：为了尽可能的满足人类的需求光纤通信系统正沿着更大容量、更高速率和更长距离的方向发展。在光通信体系中使用光的偏振复用技术,不仅能够在很大程度上提高系统通信容量还能使系统的频谱效率得到明显改善。本文在偏振复用的理论之上设计了偏振复用系统,且系统采用传输性能相对优越的DQPSK调制。最后针对本文系统进行仿真,首先,仿真了在传输链路中存在色度色散、偏振模色散的情况下偏振复用系统传输链路的性能,在此基础上对色度色散进行了补偿,并仿真分析了全光补偿与电光补偿的补偿能力的强弱。其次,对本文设计的通信系统进行了整体仿真,分别仿真分析了零距离背靠背的传输以及通过不同距离的光纤传输的系统性能。
[Abstract]:In order to meet the human needs as much as possible, the optical fiber communication system is developing along the direction of larger capacity, higher speed and longer distance. The use of polarization multiplexing in optical communication systems can not only improve the communication capacity of the system to a great extent, but also improve the spectral efficiency of the system. Based on the theory of polarization multiplexing, a polarization multiplexing system is designed in this paper, and the system adopts DQPSK modulation with superior transmission performance. Finally, the simulation of the system is carried out. Firstly, the performance of the transmission link of polarization multiplexing system is simulated in the presence of chromatic dispersion and polarization mode dispersion in the transmission link, and the chrominance dispersion is compensated on this basis. The compensation ability of all-optical compensation and electro-optic compensation is simulated and analyzed. Secondly, the communication system designed in this paper is simulated, and the performance of zero-distance back-to-back transmission and optical fiber transmission over different distances is analyzed respectively.
