随着光网络的快速发展,系统的传输码率逐渐提升,传输技术也不断地发展和完善。光纤传输系统中的各种因素造成的影响程度也出现了很大的变化。针对偏振模色散(PMD)对高速光纤传输系统造成的损害,对目前光域和电域的PMD补偿技术进行详细的阐述。通过比较各种方案,指出高速光纤传输系统中PMD的光域补偿技术更适用,发展空间大,而且性能好。其中光纤光栅补偿技术应用广泛,对单信道和多信道传输系统都适用。因此,光纤光栅技术最具发展潜力。
With the rapid development of optical networks, the transmission rate of the system is gradually increased, and the transmission technologies are continuously developed and perfected. The impact of various factors in optical fiber transmission systems has also changed dramatically. Aiming at the damage caused by polarization mode dispersion (PMD) to high-speed optical fiber transmission system, the PMD compensation technology in the optical domain and electric domain is expounded in detail. By comparing various schemes, it is pointed out that the optical domain compensation technology of PMD in high-speed optical fiber transmission system is more applicable, has more development space and better performance. Fiber grating compensation technology which is widely used, single channel and multi-channel transmission systems are applicable. Therefore, fiber grating technology has the most potential for development.
