摘　　要：通过对MCVD多模光纤进行高温通氢实验和对样品在空气中恢复情况的测量,提出了一种估算氢分子与氢氧根对1.3μm、1.55μm处影响损耗增加的方法。用导出公式对光纤中由氢引起的损耗增加进行了预测。The method estimating effects of hydrogen molecule andhydroxyl on loss increase at 1.3μm, 1.55μm is proposed, from the testand measurement for MCVD multimode fiber that exposed to a hydrogenatmosphere at high temperature and restoring in air.The loss increase ofoptical fiber due to hydrogen is predicted by the formulas.
