SLOTTED ROD FOR OPTICAL FIBER CABLE AND OPTICAL FIBER CABLE USING THE SLOTTED ROD

摘要

The outer peripheral portion of the optical fiber storage body 12 of the optical fiber cable slot rod 10 is for forming the optical fiber receiving groove (14). At least a forming area of ​​the optical fiber storage groove 14 of the optical fiber storage body 12 are constituted by a foamed material, prevent the deterioration of the flexible slot rod 10. An inner peripheral surface portion in contact with at least an optical fiber of the optical fiber receiving groove 14 is provided to form an enhancement layer which surface is smooth. By accommodating the optical fiber in the optical fiber receiving groove (14) forms an optical fiber cable covered with a covering layer on the outside of the slot rod 10. Do not have an optical fiber housed in the optical fiber receiving groove (14) being bent by a wall of the groove, it is possible to prevent a light loss increase of the optical fiber.
