Abstract

A newly designed 7.3-m high tower is reported that is equipped with a 10-kW curing system capable of coating a fiber with 50-,μm thickness of UV curable resin at a speed in excess of 5 m/sec. Performance of fibers coated at two different speeds (Vf = 1.5 and 5 m/sec) were evaluated. It was found that there were no noticeable differences in the measured values of mechanical and optical properties such as strength, coating thickness, transmission loss, bandwidth.
