Patent ID: 6859593

Claim:
A method of manufacturing an optical fiber ribbon comprising a number N greater than 1 of separable subsets disposed in a common plane, the method comprising the following steps: arranging N groups of optical fibers so that the fibers in any one group are disposed in the same plane; applying a first layer onto each group of optical fibers in order to form first casings, each first layer being of a first liquid resin that is settable under the action of UV type radiation; applying “first” irradiation to the first layers using UV type radiation in order to form first matrices; applying a second layer arranged to connect together adjacent first casings, said second layer being of a second liquid resin settable under the action of UV type radiation, all of the optical fibers being disposed in a common plane; and applying “second” irradiation to the second layer using UV type radiation to form a second matrix referred to as a “link” matrix; wherein said first and second irradiation steps correspond to a single irradiation step, and wherein said application of the second layer is performed before said single irradiation step.
