光纤浸水模拟试验探讨

Discussion on simulated test of optical fiber immersed in water

光纤浸在酸性溶液中的模拟试验表明,在受试光纤尾端测得的出纤光功率,随着试验时的溶液温度变化而明显变化。当溶液温度降低时,受试光纤的衰减变大,受试光纤出纤功率变小;反之变大。认为由温度变化引起的光纤微弯是造成衰减的主要原因。

By means of immersing optical fiber in acid water, it was indicated that the output power which was measured at the end of the tested optical fiber varied as water temperature varied. When water temperature dropt, the attenuation of the tested optical fiber would increase. Vice versa. It was discussed that micro bending caused by temperature varying was the main factor for attenuation.
