高气密性多芯光纤穿舱连接器的设计与实验验证
|
摘要
针对光纤传感技术在空间环境模拟设备内部高真空热环境下应用难题,提出了一种高气密性多芯光纤穿舱连接器。设计了基于硅胶密封技术的光纤直通穿舱连接器结构,并进行了漏率检测实验与插入损耗实验验证。实验表明,该光纤穿舱连接器的漏率小于1.0×10~(-7)Pa·L/s,最低漏率可达1.0×10~(-10)Pa·L/s,1550 nm波段下插入损耗为±0.07 dB,小于±0.1dB,满足设计要求,解决了光纤连接器的高气密性密封连接技术难题,实现了光信号无损传输的同时保持空间环境模拟设备内部的高真空度(压力<1.0×10~(-4)Pa),可以用于开展型号真空热试验。
A novel type of multicore fiber optic penetration connector with high air-tightness,dedicated to the space environment simulator,was designed,fabricated and tested.The original work focused on the connection of the optical fiber and vacuum sealing of the connector.The leakage rate was measured with helium leak detector and the insertion loss of the connector was evaluated with 1550 nm fast laserinterest region transform(FLIRT).The test results show that the newly-developed high air-tightness optical connector satisfies well the technical requirements of the vacuum thermal test.To be specific,the leakage rate was lower than 1.0 × 10~(-7) Pa·L/s,with a minimum of 1.0 × 10~(-10) Pa·L/s,ensuring the pressure in the test chamber below 1.0 × 10~(-4) Pa;the insertion loss at 1550 nm window was found to be ± 0.07 dB,smaller than the requirement of ±0.1 dB.
