摘　　要：损耗和非线性是影响超100Gbit/s高速光通信系统性能最为关键的因子。文章设计并研制了一种适合400Gbit/s高速传输用的新型单模光纤,该光纤具备超低损耗与超大有效面积特性,在1 550nm波长处衰减为0.165dB/km,在1 625nm波长处衰减为0.179dB/km;在1 550nm波长的模场直径为13.96μm,有效面积为153μm2。该光纤具备优良的抗弯曲性能,其关键技术指标优于当前国际技术水平,可为下一代高速光纤通信提供关键基础材料支撑。Loss and nonlinearity are the most critical factors affecting the performances of 100 Gbit/s optical communication systems.This letter designs and develops a novel single-mode fiber for 400 Gbit/s high-rate transmissions.With ultra-low-loss and super-large effective area characteristics,its attenuation coefficients are reduced to 0.1 65 dB/km at 1 550 nm and 0.1 79 dB/km at 1 625 nm respectively.The mode-field-diameter is 13.96 μm at 1 550 nm,and the effective area is 1 53 μm2 . Moreover,this fiber has outstanding anti-bending performance and its key technological specifications are superior to the cur-rent international technological level and can provide the key fundamental material support to the next generation high-rate fi-ber-optic communications.
