摘要： PROBLEM TO BE SOLVED: To alleviate restriction of bending directions of optical fibers arranged in parallel to enhance degree-of-freedom and to improve terminal workability.SOLUTION: An optical fiber ribbon 10 comprises: multiple optical fibers 1 arranged in parallel; and a fixing material 2 which links and integrates the multiple optical fibers 1. The fixing material 2 is provided on one of surfaces formed by the multiple optical fibers arranged in parallel, and is strip-like material bonded to the respective optical fibers 1. The fixing material 2 has flexibility. Bending the fixing material 2 changes an arrangement direction of the optical fibers arranged in a linear state into a curved shape. Thus, restriction of bending directions of the optical fibers is alleviated and terminal workability can be made excellent since an arrangement of the optical fibers 1 is not disrupted due to the fixing material 2.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber cutting device that can be operated by one action to securely provide proper tension to an optical fiber, and then cut it. SOLUTION: As an optical fiber element wire A is clamped on a slide base 17, a lever 12 is pulled toward a handle 11, so that a tension providing spring 20 is pulled through a tension providing link 22 to provide tension to the slide base 17. As the lever 12 is then pulled further, a cutting actuation permitting link 32 is actuated to rotate a cutting actuation permitting link 29 clockwise by a rotary blade actuation spring 30. A cutter base 28 is thus moved up to form a cut in the optical fiber element wire by a cutter 27, and it is broken by tension of the tension providing spring 20. COPYRIGHT: (C)2004,JPO&NCIPI
