摘要: 对单模光纤弯曲损耗系数随弯曲半径变化的理论公式进行了仿真,测量了单模光纤1550 nm时在常温和高温高湿条件下缠绕1圈时的弯曲损耗系数,测量结果绘制成曲线并与仿真得到的理论曲线进行了比较。测量了光纤在常温、高温高湿、盐雾、硫化条件下缠绕2~4圈时的弯曲损耗系数,并与缠绕1圈时的弯曲损耗系数进行比较。通过比较找出差异并分析其产生的原因。结果表明在这4种环境中,弯曲半径15~23 mm的光纤的弯曲损耗系数随缠绕圈数近似呈线性关系。

Abstract: Theoretical formula of single-mode fiber bending loss coefficient change with bending radius is simulated. The bending loss coefficients of single-mode fiber winding in 1 circle under normal and high temperature and humidity conditions at 1550 nm are measured. The measured results are drawn into curves and compared with the theoretical curves obtained by simulation. The bending loss coefficients of fiber binding in 2, 3 or 4 circles under normal temperature, high temperature and humidity, salt mist and vulcanization are measured and compared with those in 1 circle. The difference is identified and the reason caused that are analyzed by comparison. Results show that the bending loss coefficients of the fibers with bending radium from 15 mm to 23 mm are approximately linear with the winding circle number in these four environments.

Key words: fiber, bending loss, high temperature and humidity, salt mist, vulcanization
