    • The present invention relates to a method for accurately calibrating fusion temperature in optical fiber splicing. With assistance of direct arc-recentering technique, two optical fibers are spliced and then continuously heated with a post-fusion process. In the process, the fusion temperature is automatically determined in terms of effective fusion currents, which is done by real-time monitoring the fusion time dependence of cladding diameter reduction. In comparison with model calculations, variations of fusion temperature caused by changes of electrode condition and operating environment, e.g. altitude, temperature and humidity are derived. To recover the optimal fusion temperature in various fusion processes, the calibrating results are automatically invoked to compensate fusion currents.
    • 本发明涉及一种精确校准光纤拼接熔化温度的方法。 借助于直接电弧重合技术,将两根光纤拼接,然后用后融合工艺连续加热。 在此过程中,融合温度根据有效融合电流自动确定,这通过实时监测包层直径减小的融合时间依赖性来实现。 与模型计算相比,由电极条件和操作环境的变化引起的融合温度的变化,例如, 导出高度,温度和湿度。 为了恢复各种融合过程中的最佳融合温度,自动调用校准结果来补偿融合电流。
