摘要
本文基于传统G.652D光纤与G.654E超低损耗光纤的主要技术特性对比,对单跨段的100Gb/s DWDM系统采用超低损耗光纤进行实验测试,然后介绍了国家广电光缆干线网某个10Gb/sDWDM现网系统和理论采用超低损耗光纤后的性能指标对比,并进行了实验测试验证和建网投资对比分析,最后探讨了超低损耗光纤在国家广电光缆干线网应用中的必要性。
After the comparison of the main technical characteristics between the traditional G.652.D optical fiber and G.654.E ultra-low loss optical fiber,this paper introduces the ultra-low loss optical fiber which is applied and tested in the single-span 100Gbit/s DWDM system.Then it introduces the performance of 10Gbit/s DWDM system in the national radio and television cable backbone network and the theoretical application of ultra-low loss optical fiber.At the same time,we carried out the experimental verification and comparative analysis of network construction investment.Finally,the necessity of ultra-low loss optical fiber in national radio and television cable backbone network is discussed.
