1. An optical fiber ribbon formed by bonding a plurality of optical fibers in parallel,
wherein a pair of adjacent optical fibers among the plurality of optical fibers are bonded to each other through a plurality of bonding regions spaced apart from each other in a longitudinal direction of the optical fibers,
wherein an average horizontal separation force for separating the pair of optical fibers from each other in a direction parallel to the longitudinal direction of the optical fibers is 300 gf or more in each of the bonding regions, and
wherein an average vertical separation force for separating the pair of optical fibers from each other in a direction perpendicular to the longitudinal direction of the optical fibers is 8 gf or less in each of the bonding regions.
