Abstract

The technical solutions of double-cladding waveguide structure and pure SiO

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 1 550 nm of the ULA-130 fibre was 0.159 dB/km

133 μm

and 1.67×10

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.
