摘要
研究了G.652光纤在-60～80°C的色散温度特性。高精度的色散测试表明,光纤的零色散波长位移与环境温度间存在线性关系(0.024nm/°C),且整个色散曲线向长波长方向平移。进一步的理论分析表明温度变化会影响光纤折射率的变化,从而影响光纤的材料色散。
The temperature dependence of chromatic dispersion of G.652 fibers in the range of (-60)～80(°C) is investigated. High accurate dispersion measurement demonstrates a linear relationship (0.024 nm/(°C)) between the zero dispersion wavelength of fibers and the ambient temperature, and the dispersion curve shifting towards longer wavelength. Further theoretical analysis shows that the temperature variation will affect fiber's refractive index, hence affecting the material dispersion of fibers.
