An intermittent connection-type optical fiber ribbon including: optical fibers aligned in a width direction of the intermittent connection-type optical fiber ribbon; and a connection part disposed between two separation spaces that are aligned in a lengthwise direction of the intermittent connection-type optical fiber ribbon and that separate adjacent ones of the optical fibers. A percentage content of the air bubbles is equal to or less than 15.5%. The percentage content of the air bubbles is a proportion of a total area of the air bubbles contained in the connection part to an area of the connection part in a section acquired by cutting the intermittent connection-type optical fiber in the width direction.

Intermittent connection-type optical fiber ribbon, and method for manufacturing intermittent connection-type optical fiber ribbon

A method for manufacturing an intermittently-fixed optical fiber ribbon includes: collectively coating a plurality of optical fibers with a coating material by applying an uncured coating material that intrudes between the plurality of optical fibers and curing the intruded uncured coating material; and cutting the coating material positioned between the plurality of optical fibers at a predetermined interval in a longitudinal direction of the optical fibers with a plurality of rotary blades disposed side by side in a width direction orthogonal to the longitudinal direction, while delivering the collectively-coated optical fibers at a velocity Vin the longitudinal direction. The velocity Vis greater than a peripheral velocity Vof the plurality of rotary blades.
