This paper describes the fiber unit blowing length of an optical fiber distribution system for business buildings which employs pipe cable, fiber units and the fiber unit blowing technique. The relationship between the applied force and the length of a fiber unit blown into a straight pipe is investigated theoretically and experimentally and the fiber unit blowing length is estimated. Moreover, the pipe bending radius which has a small bending resistance force is clarified. Cables, fiber units and unit blowing equipment are manufactured based on the results and their transmission and mechanical characteristics are confirmed to be stable.
