Patent number: 10254482Abstract: Provided is a low-loss mode scrambler in which a steady mode distribution can be obtained in a short distance and switch to an entire mode distribution state is easy even when incident light is smaller than a numerical aperture of a fiber to be measured in a multimode fiber having a core diameter exceeding several tens of ?m and a numerical aperture of 0.2 or more. One fiber 2 is wound around a plurality of bobbins 3a and 3b having a radius larger than a minimum bending radius of the fiber to form a bundle, and the fiber 2 is twisted by rotating the bobbins 3a and 3b to form a twisted portion 5, whereby it is possible to perform output of a steady mode from light incident on the fiber 2.Type: GrantFiled: July 15, 2016Date of Patent: April 9, 2019Assignee: ADAMANT CO., LTD.Inventors: Yasuhiro Hyakutake, Yoshitada Beppu, Koji Horiguchi, Tadahisa Iikubo

Patent number: 8419294Abstract: An optical connector is provided to reliably hold a ferrule assembly in a housing to enable it stable optical connection. The optical connector is able to accomplish stable connection without any concern of displacement of an optical connecting end portion of the ferrule, even if the optical connector is subjected to repeated connecting and disconnecting operations. In the optical connector, a ferrule assemble having a polygonal prism-shaped flange is accommodated and held so as to elastically reciprocate in a housing of a cavity which has a polygonal engaging portion to receive and engage the flange of the ferrule assemble. A protrusion is formed at an end part of each engaging wall in the direction of inserting the ferrule assemble to rise toward an insertion opening for the ferrule assemble, and each protruding portion of the protrusion is provided to have each different rising height thereof.Type: GrantFiled: March 25, 2009Date of Patent: April 16, 2013Assignee: Adamant Kogyo Co., Ltd.Inventor: Yasuhiro Hyakutake
