Abstract: 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.

Abstract: It is an object of the present invention to suppress a coating resin from being shaved off in an event where optical fibers are sent out from a coating dice. When a Young's modulus of ultraviolet curable resins 13 located on outermost layers of optical fibers 3 is 300 MPa or more, and the Young's modulus is 300 MPa to 600 MPa, a plurality of the optical fibers 3 in which friction force measured by the following measurement method is 0.3 N or less are arranged in parallel to one another, these respective optical fibers 3 are fixed to one another intermittently along a longitudinal direction thereof, and adhered portions 5 are formed.
