DUAL-COLOR COATING OF OPTICAL FIBERS WITH UV CURABLE INKS

摘要

A method of coating a silica-silica optical fiber, comprising, in a single pass on a fiber coating machine: applying a primary layer of UV curable acrylate carrying a first color, on said fiber; and applying a second layer of UV curable acrylate carrying a second color different from the first color, on top of the primary layer, the second layer being applied in patterns over the primary layer. The method is used to identify fibers in bundles or loose tubes where there are more fibers than there are basic colors.
