介绍了一种大有效面积单模光纤的数值设计分析与 PCVD(等离子体化学气相沉积)制备工艺,该光纤的有效面积达到133μm2,同时在1550 nm 处衰减系数优化到0.183 dB/km,弯曲损耗优化至0.45 dB/圈(弯曲半径7.5 mm)。在双偏振DFT-S CO-OFDM 4QAM/16QAM(4进制/16 进制正交振幅调制的离散傅里叶变换扩展相干光正交频分复用)调制信号下,对该光纤在100 Gbit/s 和400 Gbit/s 系统的误码率和 Q 值等传输性能进行了验证。结果表明,该光纤能有效改善最佳入纤功率和非线性效应,可使传输距离提升30%,能有效优化400 Gbit/s 传输系统,并且在 FTTx 领域有着广泛的应用前景。

This letter numerically analyzes and experimentally confirms by PCVD process a large effective area single-mode opti-cal fiber.Its effective area is as high as 133 μm2 with its attenuation coefficient optimized to 0.183 dB/km and its bending loss to 0.45 dB/turn at 7.5 mm bending radius at 1 550 nm by using a trench structure.Furthermore,it verifies the propagation performances of the 100 Gbit/s and 400 Gbit/s systems such as BER and Q factor with dual polarization DFT-S CO-OFDM 4QAM/1 6QAM modulated signals.The results show that this fiber effectively improves the optimum incident power and the nonlinear effects and extends the propagation distance by 30% and that can effectively optimizes the 400 Gbit/s transmission system and has broad prospects of applications in FTTx.
