摘要
针对高功率光纤激光系统中光纤对接端面产生水雾凝结的问题,分析出产生该问题最重要因素为连接器不具备防潮密封性能,对其结构装配及使用过程进行剖析,同时指出其防潮密封缺陷原因,进行技术创新与工艺改进,设计了防潮密封型光纤连接器。介绍了该新型连接器防潮密封原理及结构组成;重点对该新型光纤连接器性能进行全面测试,包括浸水试验、恒定湿热试验、在线运行应用验证等。试验结果表明,其插入损耗小于0.2 dB,防潮密封性能良好,取得较好的预期效果。
Abstract
Aiming at the problem of water mist condensation on the fiber end face in a high-power fiber laser system, the most important factor causing this problem is that the traditional optical fiber connector does not have the moisture-proof sealing performance. The connector structure assembly and use process are analyzed in-depth, and the causes of the moisture-proof seal defects are pointed out. Through technological innovation and process improvement, a moisture-proof seal fiber connector is designed and completed. The principle and structure of the moisture-proof seal of the new connector are introduced. The main performances of the new connector are tested comprehensively, including immersion test, constant damp heat test, online application test. The experimental results show that the new connector has a better moisture-proof seal with IL less than 0.2 dB.
