Abstract
Official abstract text for this publication.
An optical fiber ribbon includes a plurality of optical fibers and a ribbon matrix having an inner matrix surrounding and encapsulating the optical fibers, wherein the inner matrix is the cured product of an inner matrix composition substantially free of oligomer components, and an outer matrix surrounding the inner matrix, wherein the outer matrix is the cured product of an outer matrix composition substantially free of oligomer components.
First claim
Opening claim text (preview).
We claim: 1. An optical fiber ribbon, comprising: a plurality of optical fibers; and a ribbon matrix comprising an inner matrix surrounding and encapsulating the optical fibers, wherein the inner matrix is the cured product of an inner matrix composition substantially free of oligomer components; and an outer matrix surrounding the inner matrix, wherein the outer matrix is the cured product of an outer matrix composition substantially free of oligomer components; wherein the inner or outer matrix comprising: at least one monomeric component present in an aggregate amount of 80 weight percent or more, wherein an aggregate oligomeric component of the matrix composition is 3 weight percent or less, wherein the at least one monomeric component comprises ethoxylated(10)bisphenol-A diacrylate monomer present in an amount of 50-65 weight percent and epoxy diacrylate monomer present in an amount of 30-40 weight percent. 2. The composition of claim 1 , wherein the at least one monomeric component is present in an aggregate amount of 85 weight percent or more, and wherein the aggregate oligomeric component is about 2 weight percent or less. 3. The composition of claim 1 , wherein the at least one monomeric component is present in an aggregate amount of 90 weight percent or more, and wherein the aggregate oligomeric component is 1 weight percent or less. 4. The composition of claim 1 , wherein the at least one monomeric component is present in an aggregate amount of 95 weight percent or more. 5. The composition of claim 1 , wherein the at least one monomeric component is present in an aggregate amount of 97 weight percent or more. 6. The optical fiber ribbon of claim 1 , wherein each of the plurality of optical fibers includes a glass fiber having a coating layer, and the inner matrix surrounds the coating layer of each of the plurality of optical fibers. 7. The optical fiber ribbon of claim 6 , wherein the inner matrix composition is different than the outer matrix composition.
