摘　　要：全球电信骨干网的单通道传输速率已经向40 Gbit/s甚至160 Gbit/s发展,光纤作为主要的传输线路,其损耗和色散阻碍了通信传输距离和容量的扩展。为了适应现有通信网的发展需要,文章结合当前流行的现场可编程门阵列(FPGA)技术,基于硬件描述语言实现了光纤技术中的偏振模色散(PMD)自适应技术,保证了PMD自适应补偿技术的稳定性。The single-channel transmission rate of the global telecom backbone networks is advancing to 40 Gbit/s or even to 160 Gbit/s and as the main transmission medium,the loss and dispersion of optical fibers impede the extension of communication distance and capacity.In order to fit in with the demand for the development of the existing communication networks,Polarization Mode Dispersion（PMD） adaptive technology is developed in the optical fiber technology on the basis of the hardware descriptive language in connection with the current FPGA technology,ensuring the stability of the PMD adaptive compensation technology.
