During the drying process, the fiber optic preform uses dry and clean gas to blow the inner and outer surfaces of the preform. Thereby achieving a drying effect. The drying machine for optical fiber preforms generally consists of two parts. Which is a drying gas blowing system and a preform storage cabinet.

Drying Machine Application

A large amount of deionized water will remain on the surface of the preform. Or the quartz material used for assembling the preform. It is necessary to dry the preform to completely remove the deionized water from the inside and outside of the preform. Otherwise it will have a serious impact on the performance of the fiber optic.
