Abstract
An optical fiber multi-ribbon and method for making the same is disclosed. The optical fiber multi-ribbon comprises N, where N is an integer greater than one, optical fiber ribbon members arranged in a common plane. Each of the N optical fiber ribbon members further comprise a plurality of optical fibers arranged in a planar array and an ultraviolet light curable primary matrix ribbonizing layer enveloping the plurality of optical fibers. The material forming the primary matrix ribbonizing layer of at least one of the N optical fiber ribbon members has a surface cure of at least about 80 percent. An ultraviolet light curable secondary matrix ribbonizing layer envelopes the primary matrix ribbonizing layers of the N optical fiber ribbon members. The secondary matrix ribbonizing layer material has a percent elongation to break greater than about 20 percent. The combination of the 80 percent surface cure of the primary matrix ribbonizing layers and the percent elongation to break greater than 20 percent of the secondary matrix ribbonizing layer provide an optical fiber multi-ribbon that has good handleability in terms of peeling of the secondary matrix ribbonizing layer from the primary matrix ribbonizing layer and good separation between the N optical fiber ribbons.
