Abstract
Official abstract text for this publication.
Provided is an optical fiber ribbon capable of concurrently ensuring mid-span access performance and cable production performance. The optical fiber ribbon 1 includes three or more optical fibers 2 arranged in parallel and connecting portions 3 connecting the adjacent optical fibers 2, the connecting portions 3 being formed intermittently in each of a ribbon longitudinal direction X and a ribbon width direction Y. The optical fiber ribbon 1 including the connecting portions 3 having split strength which is set in the range from 1.50 gf to 21.0 gf, contributes to exhibiting both the mid-span access performance and the cable production performance.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical fiber ribbon comprising three or more optical fibers arranged in parallel and connecting portions connecting the respective adjacent two optical fibers, the connecting portions being formed intermittently in each of a ribbon longitudinal direction and a ribbon width direction, wherein split strength of the connecting portions is in a range from 1.50 gf to 21.0 gf, wherein the connecting portions each is formed by filling a gap provided between the adjacent two optical fibers so as to adhere to each of the adjacent two optical fibers, the adjacent optical fibers being not in contact with each other, and wherein the connecting portions each have a thickness in cross section in the ribbon longitudinal direction perpendicular to the ribbon width direction that gradually increases in an arc from one side towards a middle, is thickest in the middle and gradually decreases in an arc towards another side. 2. The optical fiber ribbon according to claim 1 , wherein the thickest thickness of the respective connecting portions is in a range from 50 μm to 320 μm. 3. An optical fiber cable housing the optical fiber ribbon according to claim 1 .
