摘要
我国的骨干通信网上的传输速率已经向40 GB/s甚至是160 GB/s发展,传输线路以光纤作为主要的传输通道。与光纤相关的损耗和单模光纤的主要色散,即偏振模色散,不仅仅限制了光信号在通信过程中的传输距离,还很大程度上影响其通信容量。其中,偏振模色散对单模光纤高速和长距离通信的影响尤为突出。因此应现代光纤通信技术网的高速发展的需要,把当前流行的FPGA技术应用到单模光纤的偏振模色散的自适应补偿技术中,用硬件描述语言来实现,可以大大提高光纤的偏振模色散自适应补偿对实时性和稳定性的要求。
The rate in the main telecommunication network has already arrived at 40Gb/s,and even 160Gb/s, the transimitting object is mainly optical fiber .In singal mode optical fiber the loss and dispersion, not only impede the optical signal in the process of communication transmission distance, but also affect the communication capacity. For this , The polarization mode dispersion is the most awful on the high speed and long distance communication through the single mode fiber. Therefore, in order to better appeal to the needs of modem telecommunication network technology high speed development, using the current popular FPGA technology to the optical fiber polarization mode dispersion adaptive compensation technology by hardware description language ,which can greatly improve the optical fiber in adaptive polarization mode dispersion compensation technology in the real-time and stability.
