Abstract
The diameters of successive axial portions of an optical fiber being drawn are monitored and controlled by an optical measuring technique in such manner as to eliminate the effects of occasional, anomalous measurements or 'dropouts'. Measurement validity is tested by comparing, with a maximum allowable value, the difference between each successive diameter measurement and a standard for diameter measurement validity. Some examples of such a standard are provided. In addition, two embodiments of fiber monitoring systems are disclosed, as well as an overall monitoring and control system for fiber diameters.
