摘要
分析了限制超长距无中继传输通信的关键性因素,主要包括功率因素、色散因素和光信噪比因素等,并逐一对克服这些限制因素的相关技术进行了介绍,主要包括掺铒光纤放大器、色散补偿、前向纠错(FEC)和非线性抑制等技术,然后结合实际产品在电力系统中的应用进行了详细说明,最后总结出了超长距无中继传输通信系统设计的基本原则。
This paper analyses the key factors in the design of ultra long haul transmission, such as power, dispersion and Optical Signal Noise Ratio （OSNR）. It introduced Erbium-doped Optical Fiber （EDFA）, dispersion compensation, Forward Error Correction （FEC） and non-linear suppression techniques, and discusses their applications in power system. The basic principle of ultra long haul transmission design is also summed up in the paper.
