Embodiment Construction
[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0037] The present invention firstly provides an air pressure control device applied to the drawing of photonic bandgap optical fibers, Figure 2 ~ Figure 4 The structures shown respectively correspond to the first part, the second part and the third part of the air pressure control device, wherein the first part and the second part are assembled as the optical fiber air pressure control clamp 28, which is mainly used to clamp the intermediate body 3 and place the The air pressure partition, the third part is the air pressure control electrical part, which has the air pressure control function. Such as figure 1As shown, the second step of the photonic bandgap fiber drawing process is mainly to insert the intermediate body 3 drawn in the first step into the quartz sleeve 5 and draw it into a photonic bandgap fiber. There are three regions that need to be cont...
