Patent number: 10067307Abstract: Disclosed is a fiber optic splice protection device, comprising: a closure including a cover and a chassis; and at least one cable fixer for fixing cables to be spliced to the chassis of the closure. Wherein the cable fixer is a separate member separated from the chassis, and is removably mounted in the chassis of the closure; and all strength members of the cables to be spliced are previously fixed to the cable fixer before the cable fixer is mounted to the chassis of the closure. Therefore, it is possible that strength members of the cables to be spliced are once time secured to the chassis of the closure of the fiber optic splice protection device, so as to easy to implement rapid on-site installation. Further, the fiber optic splice protection device has higher mechanical strength.Type: GrantFiled: April 15, 2015Date of Patent: September 4, 2018Assignee: ADC Telecommunications (Shanghai) Distribution Co., Ltd.Inventors: Zhaoyang Tong, Jiangzhen Xia, Lei Liu, Longzhou Qi, Xingjun Cheng

Publication number: 20170269306Abstract: A fiber optic ferrule assembly is provided, which comprises a ferrule and an optical fiber received in the ferrule. The ferrule and the optical fiber are directly joined together, so as to fix the optical fiber in the ferrule. At least a part of the ferrule is directly over-molded on the optical fiber by injection molding or shrunk on the optical fiber. In the embodiments of the present invention, the ferrule is directly over-molded or shrunk on the optical fiber, so that the ferrule and the optical fiber are directly joined together. As a result, the optical fiber is stably fixed in the ferrule.Type: ApplicationFiled: August 17, 2015Publication date: September 21, 2017Inventors: Zhaoyang TONG, Longzhou QI, Lei LIU, Xingjun CHENG
