摘　　要：采用双包层的波导结构结合纯二氧化硅芯的技术方案,通过包层氟掺杂的设计与芯/包层之间粘度匹配的优化,实现了超低损耗大有效面积ULA-130型G.654.E光纤的制造,然后利用自行搭建的光纤非线性系数测量系统和自主设计的光纤宏弯损耗松绕设备,结合现有技术对ULA-130光纤的各项性能技术指标进行了研究。该光纤在1550 nm波长的衰减系数为0.159 dB/km,有效面积为133μm2,非线性系数为1.67×10^10 W−1。理论计算与技术研究结果表明,该光纤具有优异的衰减系数和非线性性能,适用于大容量、高速率和长距离光通信骨干网传输系统,相对于常规的G.652.D光纤,可以显著改善系统的光信噪比,提升系统的传输性能。The technical solutions of double-cladding waveguide structure and pure SiO2 core were taken,the G.654.E type ULA-130 fibre ultra-low-loss and large effective area was realized by F-doping design and optimization of the viscosity match between core and caldding.Then the study on various optical characteristics of the ULA-130 fibre was carried out,utilizing self-built optical fibre nonlinear coefficient measurement system and self-designed optical fibre macro-bending loss winding device,as well as the avaliable techniques.The attenuation coefficient,effective area and nonlinear coefficient at 1550 nm of the ULA-130 fibre was 0.159 dB/km,133μm2 and 1.67×10−10 W−1 separately.According to the theoretical calculation and technical analysis,the ULA-130 fibre posseses excellent attenuation and nonlinear performance,which is applicable in high capacity,high bitrate and long-range optical backbone network system.Compared to conventional G.652.D fibre,the ULA-130 fibre could improve the optical singal-noise ration and the performance of transmission system dramatically.
