FIBER PROTECTIVE TUBE FOR TERMINAL PART OF OPTICAL FIBER CABLE

摘要

PURPOSE:To prevent an increase in transmission loss at the time of fiber connecting and switching the to prevent the degradation in reliability by bending strains by providing a protective tube part made of an elastic material which discretely covers fibers to a gap part fixed to an optical fiber cable side. CONSTITUTION:A through-hole 13 through which a tension member 4 passes is provided to the center in a bottom part 12 of a blinded cylindrical cap part 11 to be fitted to a core part 6. Fiber housing tubes (tubes) 14 are provided in correspondence to the number and positions of the fibers 2 to the bottom part 12 and are communicated with the inside of the cap part 11. The cap part 11 where the tubes 14 are supported constitutes the fiber protective tube 15. Direct contact of the fibers with the other members is, therefore, obviated and the possibility of bending the fibers at a small radius when the fibers are bent is eliminated. The disturbance of smooth communication by the increased transmission loss and the degradation in the reliability by the bending strains are thereby prevented.
