摘　　要：针对由同步数字体系(Synchronous Digital Hierarchy,SDH)组成的大型环网传输地面测发网络,提出了一种通用长距离无中继光纤传输系统,具备长距离无中继传输、传输距离自适应和集成一体化的设计优点,能够实现10 Gb/s光最大传输250 km,在设计上采用分布式拉曼光放大方案,并采用无中继全光传输技术体制,整个线路中间无有源设备、无中继供电,提高整个系统可靠性,降低系统建设运维成本。For the large Synchronous Dingital Hierarchy(SDH)ground testing and launch network of ring transmission,a common repeaterless optical fiber transmission system for long distance is proposed,which has the advantages of long distance repeaterless transmission,adaptive transmission distance and integrated design,enabling the optical maximum transmission distance of 250 km at a rate of 10 Gb/s.Distributed Raman optical amplification solution,as well as repeaterless all-optical transmission technology system,is adopted in the design.There is no active equipment in the whole line without relay power supply.The reliability of the overall communication system is improved,and the cost of system operations and maintenance is reduced.
