Description
Technical field
It is specifically a kind of to be based on high power single mode guarantor/mono- inclined special light the utility model relates to high power light fiber connector
Fine moisture seal type connector.
Background technique
Conventional single-mode guarantor/single polarization fiber connector is assembled by each standard parts and components, and forming process does not seal work
Skill does not do moisture seal processing yet, in practical applications, especially long-term application on site when, conventional fiber optic connectors do not have
Moisture seal effect causes its internal moist and cleanliness not up to standard, brings seriously in optical transport, light measurement, light sensing field
In consequence, especially device of high power laser or strong optical transport and measurement application, main laser transmission is measured to used light
Not only quantity is more and new requirement is proposed to optical fiber connector for fiber connector, in this kind of focus on the application field, since optical fiber connects
It is higher to connect optical power in device, generates heat in optical fiber connector docking, when optical path disconnects, restores room temperature in optical fiber connector
In the process, being generated at water mist, especially optical fiber connector docking in has water mist condensation, leads to device of high power laser and Qiang Guang
Transmission with measuring system light loss increase, performance degradation, in addition the fibre core of optical fiber connector can be damaged and influence device and
The normal use of system analyzes its reason, and mainly conventional single-mode guarantor/single polarization fiber connector moisture seal performance is poor, specifically
It is because conventional single-mode guarantor/single polarization fiber connector makes forming process and do not do moisture seal processing when docking use with flange
Technique causes micronic dust and steam in air to enter the ferrule endface and surrounding of fiber alignment.
