200μm光纤氘气处理工艺的优化

Optimization of 200μm Optical Fiber's Deuterium Treatment Process

通过理论分析及工艺试验,对200μm光纤氘气处理工艺中的氘气浓度、工艺温度及压力进行优化,并根据工艺时间和处理成本指标对各优化后工艺参数的不同组合进行了优选,在氘气浓度为1%,工艺温度为40℃、压力为20kPa条件下实现了最优的工艺时间和处理成本。相比常规245μm单模光纤,200μm单模光纤在上述优化的工艺条件下,氘气处理工艺时间可缩短18%。同时,200μm单模光纤经优化的氘气工艺处理后,氢老化附加衰减可满足IEC等标准的要求,并且对其它通信波段的衰减没有影响,氢老化附加衰减降低是长期有效的。

Based on theoretical analysis and process test,the deuterium concentration,process temperature and pressure of 200μm optical fiber＇s deuterium treatment process are optimized.And the different combinations of optimized process parameters are optimized based on process time and treatment cost index.The optimal process time and treatment cost are achieved under the conditions of deuterium concentration of 1%,process temperature of 40 ℃and pressure of 20 kPa.Compared with the conventional 245μm single-mode optical fiber,the deuterium treatment processing time of 200 μm single-mode optical fiber can be reduced by 18% under the above optimized process conditions.At the same time,after this optimized deuterium process,hydrogen aging additional attenuation of the200μm optical fiber can meet the requirement of IEC and other standards,and has no effect on the attenuation of other communication bands,and its reduction is long-term effectiveness.
