Abstrakt: It was studied that the cure behavior of optical fiber coatings on films cured with a UV conveyor or mock fibers cured with the draw tower simulator using UV-LED. UV dose and intensity of the draw tower simulator were estimated with photo initiator consumption in a coating. Temperature of a coating or UV intensity affected their cure behaviors strongly on a primary coating, weakly on a secondary coating. Unique behaviors were appeared at low work speed in conveyor curing. They came probably from spatial distribution of intensity. In mock fiber experiment, monomer-11 contained in a primary coating showed reverse behavior. It came probably from photo initiator consumption in a coating at low line speed in high intensity curing.
