摘要
根据吐哈油田光传送网络的实际情况和建设智能油田的需要,通过对OTN技术和Ethernet技术的比较分析,提出DWDM+Ethernet比OTN技术更适合以IP数据业务和应用为主的网络,是吐哈油田下一代融合网络的最佳选择。给出了实际设计方案,方案采用了先进的前向纠错(FEC)技术解决现有光缆路由中存在的超长跨距和超大光衰耗导致的光信噪比(OSNR)低于网络技术指标要求的技术难题。
According to the actual situation of Tuha oilfield＇ s optical transmission network and the needs of building a smart oilfield, the method of DWDM added Ethernet is better suited to IP Data and application-oriented network than OTN techniques is put forward in this the paper based on the OTN technology and Ethernet technology comparative analysis. The method is the best choice for next-generation converged networks in Tuha oilfield. The actual design is given and the advanced forward error correction （FEC） technology is employed to solve the problem of optical signal-to-noise ratio （OSNR） below the network technical specifications that is induced by optical cable with ultra-long span and ultra-high optical attenuation.
