摘　　要：针对光纤损耗与非线性效应会导致光纤弯曲性能劣化的问题,设计了具有沟渠层、过渡层和适宜包芯比的折射率剖面结构G.654.E光纤,研究了G.654.E光纤的波导结构对衰减、光学性能的影响。试验结果表明:在1550 nm和1625 nm波长处,光纤的衰减典型值分别是0.162 dB/km、0.178 dB/km;弯曲半径为10 mm、绕1圈时的宏弯损耗分别低于0.04 dB、0.06 dB;弯曲半径为30 mm、绕100圈时的宏弯损耗典型值分别是0.008 dB、0.015 dB;光纤在1550 nm波长处的有效面积典型值可达130μm^(2)。Aiming at the problem that fiber loss and nonlinear effect will degrade the bending performance of optical fiber,a refractive index profile structure G.654.E optical fiber with ditch layer,transition layer and appropriate cladding ratio is designed,and the effects of waveguide structure of G.654.E optical fiber on attenuation and optical performance are studied.The test results show that at 1550 nm and 1625 nm wavelength,the typical attenuation values of optical fiber are 0.162 dB/km and 0.178 dB/km respectively.When the bending radius is 10 mm and one turn is wound,the macro bending loss is lower than 0.04 dB and 0.06 dB respectively.When the bending radius is 30 mm and 100 turns,the typical values of macro bending loss are 0.008 dB and 0.015 dB respectively.The typical effective area of optical fiber at 1550 nm wavelength can reach 130μm^(2).
