摘要
目前,特高压工程广泛使用的超低损耗光纤主要依赖于进口,文章通过在1000 kV特高压交流工程中首次应用国产G.652D超低损耗(Ultra Low Loss,ULL)光纤,成功使用此ULL光纤开通了10 Gbit/s试验电路,开通2 M及155 M测试业务并安全稳定运行,实践验证了使用国产ULL光纤的OPGW光缆在特高压线路运行的可行性,并通过半年以上长期运行监测,光纤衰耗未发生劣化,为该类型光纤推广应用奠定了基础。
At present,the ultra-low loss optical fiber widely used in UHV projects mainly depends on imports.In this paper,a 10 Gbps experimental transmission is successfully implemented based on domestic G.652D ULL OPGW fiber cable used for the first time in 1000 kV UHV project.2 M and 155 M test circuit is successfully established and runs safely and stable.Practice has verified the reliability of this type of optical cable in UHV project,and through long-term monitoring for more than half a year,the fiber loss has not deteriorated,which has laid a foundation for the promotion and application of this type of fiber.
