Abstract
Provided herein is a method of and system for processing an optical fiber. The method includes the steps of drawing an optical fiber in a drawing direction along a process pathway through a coating chamber comprising an inlet and an outlet, and a coating liquid volume to coat the optical fiber; supplying the coating liquid through the inlet, the coating liquid exiting the coating chamber through the outlet; and recirculating to coating liquid exiting the coating chamber to the inlet.
