OPTICAL FIBER RIBBON AND OPTICAL FIBER CABLE

摘要

PROBLEM TO BE SOLVED: To provide an optical fiber ribbon which allows at least one of a plurality of collectively coated optical fiber strands to be easily separated as a single core.SOLUTION: An optical fiber ribbon 1 includes a plurality of optical fiber strands 10 and 11 arranged in a parallel on a plane and a coating layer 20 integrally covering peripheries of the plurality of optical fiber strands 10 and 11. The plurality of optical fiber strands 10 and 11 include at least one first optical fiber strand 10 having a first outer diameter D1 and at least one second optical fiber strand 11 having a second outer diameter D2 smaller than the first outer diameter D1.
