Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber production, in particular to a side hole cleaning device for a preformed rod. Background Art

[0002] For the production and processing of panda-type polarization-maintaining optical fiber preform, after opening side holes on both sides of the preform, the entire preform and the hole wall need to be cleaned, and then the stress mother rod is installed in the side hole. The size of the stress mother rod is determined by the aperture of the side hole of the preform. The inner hole of the preform requires high cleanliness for the inlay installation of the stress mother rod.

[0003] However, due to the long length of the preform rod and the special position of the side hole, it is not conducive to cleaning the inner hole of the preform rod compared to the outer wall of the preform rod.
