国产超低损耗光纤在超长距离通信系统中的应用

Application of Ultra Low Loss Fiber on Ultra Long Haul Optical Communication System

随着全球IP流量的急速增长以及宽带互联网技术的不断进步,传输容量需求急剧增长,通信网规模不断扩大,特别是400G技术的兴起对超长距大容量高速率传输系统提出了更高的要求。目前国内厂家在超低损耗新型光纤方面(超低损耗G.652和G.654.E)取得了关键性突破,并在成缆测试以及实际链路中充分验证了其在超长跨距传输网络建设方面具有广阔的应用前景。

With the rapid growth of global IP traffic and the development of broadband Internet technology, the demand for transmission capacity is increasing rapidly, and the scale of communication network is continuously expanding. In particular, the rise of400 G technology puts forward higher demands on the ultra long haul, ultra large capacity and ultra high speed transmission systems. At present domestic fiber manufacturers have made key breakthroughs in novel ultra-low loss optical fibers（ultralow loss G.652 and G.654.E）. It is fully verified in cable test and actual cable link that ultra-low loss optical fibers have broad application prospects in the construction of ultra long haul transmission network.
