ABSTRACT:
A non-contact system for monitoring the tension in an optical waveguide fiber during drawing is provided. The system comprises: (a) means for sensing the motion of the fiber in a direction transverse to the direction in which the fiber is moving; (b) means for analyzing the sensed motion to determine at least one frequency component thereof; and (c) means for monitoring the frequency component so determined so as to monitor the tension in the fiber.
