Abstract
An optical fiber ribbon is manufactured under a condition where, assuming that the optical fiber ribbon has a thickness of 2d (mm), a guide roller has a diameter of 2R (mm), and a period of time till the optical fiber ribbon comes into contact with the guide roller after leaving an ultraviolet irradiation apparatus is t (ms), a relationship of d/(R+d).times.t!<0.2 is satisfied. Accordingly, no damages are imparted to the optical fiber ribbon, and no micro-bendings occur in its coated optical fibers, whereby the transmission characteristic can be prevented from deteriorating.
