Abstract

PURPOSE: To make handling easy and achieve the improvement in strength and stability of transmission characteristics by containing optical fibers in the spacers formed in U-form in section, directing tge bottom parts of the spacers to the center and aggregating and externally mounting the same around a tension member.
CONSTITUTION: A plurality of optical fibers 1 or optical fiber units 11 are contained in the plastic spacers 2 which are extrusion molded to U-form in section. These are then so aggregated as to gather on the circumference of a tension member 3 with the open parts thereof being faced upward and the bottom parts toward the center. Tapes 4 are wound on this and a sheath 5 is applied. Thereby, handling may be made easy, strength high and transmission characteristics stable.
