Overview: In the application of high-power laser optical fiber transmission and measurement, the transmission power of optical fiber is higher. With the laser disconnected, the ceramic insert core is cooled, and the water vapor in the air will condense at the end face of the connector. It will increase the fiber splicing loss and even damage the fiber end face. It is necessary to fundamentally solve the problem of water mist condensation on the end face of the connector. The most important factor of water mist condensation is that the traditional optical fiber connector does not have moisture-proof sealing performance. This paper analyzes the structure assembly and use process of the connector, and points out five defects of the moisture-proof seal. Specifically, there is no sealing process or moisture-proof sealing treatment in the assembly process. In addition, when the connector is used for the butt joint with flange, no moisture-proof sealing process has been carried out. It causes the dust and water vapor in the air to enter the surrounding and end face of the ceramic insert core. So, the internal humidity and cleanliness of the connector are not up to standard, which brings serious consequences to the field of optical transmission and optical measurement. Through technological innovation and process improvement, a new moisture-proof seal fiber connector is designed and completed without changing the original structure and size of the optical fiber connector. 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 the main optical performance test, immersion test, constant damp heat test, and online application test. The experimental results show that the new connector has better moisture-proof seal with IL less than 0.2 dB. After immersion test, the insertion loss index of the connector also meets the expected requirements. The main optical parameters meet the application requirements. The new moisture-proof sealing connector solves the problem of water mist condensation on the end face of the connector, and can be used in high power fiber laser system for a mid-long term, that will have good prospects. In the next step, we will continue to innovate and introduce this innovative technology and improved process into the single polarization fiber connector and the polarization-maintaining fiber connector. We will design and complete the moisture-proof sealing single-polarization optical fiber connector and moisture-proof sealing polarization-maintaining fiber connector to meet the new application requirements of the fiber laser system.
