摘要(Abstract)：
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1 550nm处衰减系数优化到0.183dB/km,弯曲损耗优化至0.45dB/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100Gbit/s和400Gbit/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400Gbit/s传输系统,并且在FTTx领域有着广泛的应用前景。
