ABSTRACT:
A method of uniformly coating an optical waveguide fiber 10 comprises the steps of suspending an elongated glassy optical fiber preform 11 in an upright orientation from a preform holder that includes a collet 14 to which an x-y translator 15 is coupled, heating the preform, and drawing fiber from the bottom of the heated preform. The drawn fiber is passed through a tubular coating applicator 32 located beneath the preform, and the position of the fiber is sensed as it is being drawn. In response to sensed deviations in fiber position from along a preselected path that extends through the tubular coating applicator along the applicator axis, the preform is repositioned by horizontal movement of the preform holder so as to return the drawn fiber to the preselected path and thereby maintain its travel through the coating applicator substantially along the applicator axis.
