Title:
METHOD FOR MANUFACTURING OPTICAL FIBER INTERMITTENT TAPE CORE AND OPTICAL FIBER INTERMITTENT TAPE CORE
Document Type and Number:
WIPO Patent Application WO/2018/117068
Kind Code:
A1
Abstract:
[Problem] To provide a method for manufacturing an optical fiber intermittent tape core and the optical fiber intermittent tape core that can be used for manufacturing where the linear velocity is high. [Solution] The present invention is a method for manufacturing an intermittent connection type optical fiber intermittent tape core 2 capable of high-speed formation of intermittent connected parts 3 and non-connected parts 4 while maintaining high-speed in the linear velocity for optical fiber cores 1 and the application rate for a resin composition applied for connecting adjacent optical fiber cores 1 to each other, since non-connected parts 4 and intermittent connected parts 3 can be formed simply between adjacent optical fiber cores 1 that have been made into tape cores by implementing laser processing with irradiation of optical fiber tape cores with pulse laser light. In addition, since the optical fiber tape core 1 obtained has the non-connected parts 4 and intermittent connected parts 3 formed by pulse laser light irradiation, the present invention is an intermittent connection type optical fiber intermittent tape core 2 that can assure operability during batch connections as well as being able to reliably form intermediate branching without loss of cable characteristics during high density mounting.
