MANUFACTURING METHOD OF OPTICAL FIBER RIBBON, MANUFACTURING DEVICE FOR OPTICAL FIBER RIBBON IMPLEMENTING SAID MANUFACTURING METHOD, AND OPTICAL FIBER RIBBON MANUFACTURED WITH SAID MANUFACTURING METHOD

摘要

A manufacturing method for an optical fiber ribbon, in which: a plurality of optical fibers are arranged in parallel and the neighboring optical fibers are partially coupled with each other at given intervals in a longitudinal direction to form a subunit; and the optical fibers positioned at side edges of the neighboring subunits are partially coupled with each other at a given intervals in the longitudinal direction, includes: sending out the optical fibers in a parallel manner with intervals provided therebetween, applying an uncured resin to the optical fibers, continuously changing positions at which the uncured resin is interrupted by a plurality of interrupt members, and forming coupled portions at which the optical fibers are coupled to each other by irradiating resin curing energy, wherein a moving period or phase of the interrupt members is changed for every arbitrary optical fibers.
