OPTICAL FIBER TAPE CORE WIRE AND OPTICAL FIBER CABLE HOUSING OPTICAL FIBER TAPE CORE WIRE

摘要

Provided is an optical fiber tape core wire with which it is possible to implement higher density and narrower gauges, and to mount an optical fiber in a V-shaped groove of a fusion machine without falling away. An optical fiber tape core wire (1) has three or more optical fiber cores (2) which are positioned in parallel, with two adjacent optical fiber cores (2) being coupled with coupling parts (3), and the coupling parts (3) being respectively disposed intermittently in the tape core wire longitudinal and latitudinal directions. With the optical fiber tape core wire (1), the external diameter of the optical fiber (2) is 220µm or less, and the distance (L) between the centers of adjacent optical fibers (2) is 250±30µm.
