Title: Tetsuya Yasutomi: Innovator in Optical Fiber Technology
Introduction
Tetsuya Yasutomi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical fiber technology, holding a total of 7 patents. His innovative designs and methods have advanced the capabilities of optical fiber cables, making them more efficient and reliable.
Latest Patents
Yasutomi's latest patents include an advanced optical fiber cable that features a central-core-type design without the use of slotted rods. This cable is composed of a core, a wrapper, a tension member, a ripcord, and a sheath. The core is uniquely formed by twisting together multiple optical fiber units without back-twisting. The optical fiber units themselves are created by twisting together several intermittently-fixed optical fiber ribbons, ensuring that the direction of the twisting is consistent throughout.
Another notable patent is for a method of producing an optical fiber cable and cable core. In this design, a jacket is applied to the outer circumference of the cable core, rip cord, and tension member. The cable core, rip cord, and tension member are collectively covered by the jacket, while a wrapping tape is longitudinally placed around the outer circumference of the core part. This innovative method allows for a wrap part that lies substantially straight in the axial direction of the optical fiber cable, enhancing its structural integrity.
