Latest Patents

One of his latest patents is the flat optical fiber cable. This innovative design consists of an optical fiber ribbon cord made from tensile strength fiber, which has a rectangular shape. The cable covers several optical fiber cores that are arranged parallel to one another. A sheath encases the outside circumferential part of the tensile strength fiber. The tension member runs parallel to both sides of the optical fiber ribbon cord, forming a row. This design allows for easy construction and assembly of terminals while preventing damage to the optical fiber and deterioration of performance. Another significant patent is the optical fiber core, which includes an optical fiber covered by an ultraviolet curable resinous layer. This layer is further protected by a covering layer made of flexible thermoplastic resin and a second layer of semi-hard or hard thermoplastic resin. This combination ensures that the optical fiber core meets various performance characteristics, including squeezing, tensile strength, bending, temperature, and lateral pressure, while also being economically efficient.
