摘　　要：伴随着通信技术发展水平的不断提高,远距离传输系统由最开始的准同步数字序列技术升级到同步数字序列技术,再到如今的密集波分复用技术,在短短的十年间完成了完美的三级跳,使得我国光纤通信系统整体发展水平朝着长距离、高速率、大容量、信息安全高的方向发展。特别是在密集波分复用技术的出现以及广泛应用下,使得长距离光传输的限制因素种类越来越多,在原有同步数字系列色散与损耗的基础上,又出现了偏振模色散、光信噪比等限制因素。文章针对长距离光传输限制因素的有效解决措施展开详细分析,为我国通信技术整体发展水平进一步提高奠定坚实的基础。With the continuous improvement of the development level of communication technology,the long-distance transmission system has been upgraded from the initial quasi-synchronous digital sequence technology to the synchronous digital sequence technology,and then to the current dense wavelength division multiplexing technology,which was completed in just ten years With the perfect triple hop,the overall development level of my country's optical fiber communication system is moving towards the direction of long distance,high speed,large capacity and high information security.Especially with the emergence and wide application of dense wavelength division multiplexing technology,there are more and more limiting factors for long-distance optical transmission.Based on the dispersion and loss of the original synchronous digital series,polarization mode dispersion and optical Limiting factors such as signal-to-noise ratio.This paper analyzes the effective solutions to the limiting factors of long-distance optical transmission in detail,and lays a solid foundation for the further improvement of the overall development of my country's communication technology.
