Intermittent connection type optical fiber tape core wire, its manufacturing method, optical fiber cable and optical fiber cord

摘要

A plurality of two-fiber optical fiber ribbons that are integrated by bringing two optical fiber wires into contact with each other, and a connecting portion in which the adjacent two-fiber optical fiber ribbons are connected to each other; An intermittently connected optical fiber ribbon in which unconnected portions are intermittently provided in the longitudinal direction, the outer diameter of the optical fiber being 0.22 mm or less, and adjacent Between the two-core optical fiber ribbons, the center-to-center distance between adjacent optical fiber cores with the connecting portion interposed therebetween is 0.28 ± 0.03 mm.
