Abstract

The invention relates to an isolated optical fiber seal switching device and a machining method thereof. The isolated optical fiber seal switching device comprises an inboard flange, an outboard flange and a glass-to-metal sealing window. The glass-to-metal sealing window is welded on the outboard flange. The inboard flange is fixed with the outboard flange from the inside of a container and clamps the glass-to-metal sealing window between the inboard flange and the outboard flange. The outboard flange is used for being in seal connection with a container interface from the outside of the container. The inboard flange is provided with at least one collimator mounting hole. The outboard flange is provided with collimator mounting holes of which the quantity and position correspond to those of the collimator mounting holes on the inboard flange one by one. The inside of each collimator mounting hole is fixed with an optical fiber collimator. The glass-to-metal seal window comprises optical glass and a thin-wall metal tube with a flanging. The isolated optical fiber seal switching device and the machining method thereof solve the problem that easily-aged organic materials are used to seal an optical fiber, which cannot meet the requirement on seal timeliness in the prior art, and have the advantages of prolonging the service life of sealing equipment and improving the sealing performance.

Description

technical field [0001] The invention relates to a device for sealing and transferring an optical fiber group and a processing method thereof, in particular to a device for sealing and transferring an optical fiber group drawn out of a sealed explosion container and a processing method thereof. Background technique [0002] When using a sealed explosion container for experiments, both the explosive device and the detection system are placed in the explosion container, and the detection system captures the signal generated at the moment of the explosion and then passes through the transmission line to the recording device. [0003] The measurement system using optical fiber as the transmission line has been widely used in other fields because of its wide transmission frequency bandwidth, strong anti-electromagnetic interference ability, and low transmission loss. In view of the superiority of optical fiber transmission, it is imperative to apply it to the experiment of sealed ...
