Abstract
Apparatus and process for automatic control of the production of optical fiber are disclosed. The process comprises continuously depositing and sintering borosilicate glass particles on a fused silica rod or a graded index rod in such a manner that the glass exhibits a uniform, radially increasing concentration of boron. The appropriate boron oxide/silica concentration ratio in the glass particles is controlled by the time of deposit and the weight and diameter of the rod, which are continuously monitored. The concentration of boron oxide and silica in the particulate is likewise continuously monitored to insure that the correct portion of boron oxide/silica is deposited. The apparatus for conducting the process, includes means for continuously monitoring the weight and diameter of the rod and the boron oxide content of the glass particles and means for automatically regulating the equipment used to produce the optical fiber in response to readings from the monitoring means.
