Abstract
A method for manufacturing an intermittent bonding type optical fiber ribbon which is capable of forming non-connection portions and intermittent connection portions between adjacent coated optical fibers formed into an optical fiber ribbon by performing a laser processing for the ribbon through irradiation with a pulse laser light, thereby making it possible to rapidly form the intermittent connection portions and the non-connection portions while maintaining high linear velocity of the coated optical fiber. The non-connection portions and the intermittent connection portions are formed in the obtained intermittent bonding type optical fiber ribbon through the irradiation with the pulse laser light, so the intermittent bonding type optical fiber ribbon becomes the intermittent bonding type optical fiber ribbon, which is capable of securing operability during collective connection and surely being subjected to an intermediate branching without damaging cable characteristics during high density mounting.
