Tetsuhiro Numata is a prominent inventor based in Tsukuba, Japan. He has made significant contributions to the field of optical fiber technology, holding a total of 3 patents. His innovative methods and devices have advanced the efficiency and effectiveness of optical fiber splicing.

Latest Patents

Numata's latest patents include a method of splicing optical fiber and an optical fiber splicing device. The method involves splicing a first optical fiber cable with an optical fiber in a splicing box. This process is designed for drop cables or indoor cables, where the optical fiber is drawn from a second optical fiber cable. The method includes sliding a unit base that holds an extended-optical-fiber-attached splice along a rail towards a grasper. This allows for the insertion of an optical fiber grasped by the grasper between the halved elements of a mechanical splice. The splicing is achieved by butt-jointing the end of the inserted optical fiber to the extended optical fiber.

Another patent focuses on a mechanical splice unit and an optical fiber splicing method. This mechanical splice unit features an optical fiber guide groove formed at the matching surfaces of both a base and a lid. It is capable of grasping a first optical fiber at one end side of the lid. The optical fiber splice auxiliary tool is designed to assist in the splicing of the first optical fiber, which is held by the mechanical splice.
