スロット形光ファイバテープケーブルにおけるスロットロッドの変形挙動の解析

抄録

By applying Love's equilibrium equations, the forces and bending moments in slot rods of an optical fiber cable have been determined. The deformation of the slot rod subjected to the forces and bending moments just derived has been analyzed by means of the three-dimensional finite element method. The results for the cable with 600 optical fibers showed that the deformation of the slot was so small that the clearance between the fiber tapes and the lateral wall of the slot was sufficient when the cable was subjected to the extentional strain of 0.1 % and the curvature due to bending was not larger than 1/1100 1/mm.
