An object of the present invention is to provide a production method for producing an optical fiber ribbon that has an identification mark for identification, in which optical transmission loss is unlikely to be caused. A production method for producing an optical fiber cable for achieving the above objective includes: curing a photocurable resin by irradiating the photocurable resin with light, the photocurable resin being disposed to couple together a plurality of single-core coated optical fibers arranged in parallel; and forming a plurality of identification marks on the photocurable resin cured, the forming being performed by applying ink by an ink-jet method, in which the forming the plurality of identification marks is performed in a state in which a temperature of the photocurable resin is lower than or equal to 37.3° C.

Production method for producing optical fiber ribbon

An optical fiber ribbon including a grating formed by a simple method is provided. The optical fiber ribbon includes a plurality of single-core coated optical fibers disposed parallel to each other, and a tape layer that covers the single-core coated optical fibers and partially connects adjacent single-core coated optical fibers. The single-core coated optical fibers include a grating part based on a plurality of strained parts formed in the tape layer at regular intervals in the longitudinal direction of the single-core coated optical fibers.

Optical fiber ribbon and method for producing optical fiber ribbon

An optical fiber ribbon manufacturing device comprising: a tape diefor coating a plurality of single-core coated optical fiberswith a photocurable resin; a split diefor forming a split portion in the photocurable resin present between the single-core coated optical fibers; and a light irradiation devicefor irradiating the photocurable resin with light to cure the photocurable resin, wherein both the tape dieand the split dieare temperature-controlled or only the split dieis temperature-controlled, a temperature of the tape dieis higher than a temperature of the split die, and the temperature of the split dieis lower than the temperature of the tape die
