ABSTRACT:
An improved method of coating an optical fiber is disclosed. A transducer is submerged in a container of liquid coating material and activated so that it causes the formation of a wave of coating material within the container. The optical fiber is then drawn through the container and through the wave, the wave counterbalancing the negative meniscus produced by drawing the fiber through the container. A curved housing also may be placed in the container and surrounding the transducer for controlling the size, amplitude, shape, or direction of the wave. A plurality of transducers also advantageously may be used.
