Title:
INTERMITTENT CONNECTION TYPE OPTICAL FIBER RIBBON, MANUFACTURING METHOD FOR INTERMITTENT CONNECTION TYPE OPTICAL FIBER RIBBON, OPTICAL FIBER CABLE AND OPTICAL FIBER CORD
Document Type and Number:
WIPO Patent Application WO/2017/145955
Kind Code:
A1
Abstract:
The objective of the present invention is to provide an intermittent connection type optical fiber ribbon capable of increasing the density of optical fiber cables and optical fiber cords, and an optical fiber cable and an optical fiber cord using the intermittent connection type optical fiber ribbon. In the intermittent connection type optical fiber ribbon, at least some of a plurality of optical fiber cores (11A-11L) arranged in parallel are in contact with one another, and a connection part in which the space between the neighboring optical fiber cores is connected by an adhesive resin (3) and a non-connection part in which the space between the neighboring optical fiber cores is not connected by the adhesive resin are intermittently provided in a longitudinal direction between some or all of the optical fiber cores, wherein the outer diameter dimension of the optical fiber cores is no greater than 0.22 mm and the center-distance between the neighboring optical fiber cores is 0.20 ± 0.03 mm.
