摘要
由于光信号和光纤具有损耗、色散、非线性等特性,光纤通信网的超长距传输通常会受到影响。通过配置光纤拉曼放大器,引入泵浦技术以及FEC等技术,可以实现超长距传输系统。
For the characteristics of optical signal and optical fiber,the ultra-long span transmission in optical fiber communication network is restricted.To realize the ultra-long span transmission system,this paper proposes some solutions,including Raman Fiber Amplifier(RFA),Remote Optically Pumped Amplifier(ROPA) and technology of FEC.Finally,it puts forward a scheme of unrepeated and ultra-long span transmission which is based on high power amplifiber and Remote Optically Pumped Amplifier,and then ananysizes its advantage.
