Patent number: 7641397Abstract: The head end surface of an optical fiber (2) and the head end surface of an optical fiber (12) are butted to each other in an alignment member (22) of an adapter (21). In the butting, because one of the members clasping the optical fiber (2) is a plate (4a) that is short, the optical fiber (2) is bent and buckled between the left end of the short plate and the right end of the alignment member. Members clasping the optical fiber (12) are a long plate (14b) and a V-grooved base plate (13), and the optical fiber (12) is therefore horizontally fixed between each of right ends of the long plate and of the V-grooved base plate (13) and the left end of the alignment member. This results that the head end surface of the optical fiber (2) and the head end surface of the optical fiber (12) are in tight contact with each other, achieving excellent optical transmission between both optical fibers.Type: GrantFiled: August 31, 2004Date of Patent: January 5, 2010Assignees: Japan Aviation Electronics Industry, Limited, Nippon Telegraph and Telephone Corporation, Hirose Electric Co., Ltd.Inventors: Yuichi Koreeda, Akihiro Onogawa, Yoshiteru Abe, Masaru Kobayashi, Ryou Nagase, Masahiro Tsuchida, Koichi Arishima

Patent number: 7620280Abstract: A filled-core optical fiber (100) spliced to conventional, solid core optical transmission fiber (175) and a related method of making the same are provided. The optical fiber (100) comprises a core region (140), a cladding ring (120) enclosing the core region (120), and an outer cladding layer (160). A fill hole (115) is formed in the optical fiber (100) which extends from an outer sidewall (110) to the core region (140). The fill hole (115) is for introducing optical material (165) into the core region (140). The optical material (165) is introduced into the core region (140) after opposing ends (121, 122) of the optical fiber (100) are spliced to the free ends (176, 176) of conventional, solid core optical transmission fiber (175). The optical material (165) is introduced into core region (140) after splicing to avoid damage to the optical material (165) due to exposure to high temperatures generated during splicing.Type: GrantFiled: September 5, 2007Date of Patent: November 17, 2009Assignee: Harris CorporationInventors: Timothy E.

Patent number: 7553091Abstract: The connector modules that are designed and shaped to mate with one side of the receptacle of the panel have mating devices that enable them to be stacked one atop the other inside of the receptacle in a relatively rigid stack. The connector modules that are designed and shaped to mate with the other side of the receptacle of the panel have mating devices that enable them to be held in slots that are slightly separated from one another by air gaps to allow them to “float” in the receptacle. By floating the connector modules in one side of the receptacle while having a relative rigid stack of connector modules in the other side of the receptacle, it is ensured that very precise optical alignment will be maintained between the respective lenses in the connector modules that face each other in the receptacle.Type: GrantFiled: May 21, 2007Date of Patent: June 30, 2009Assignee: Avago Technologies Fiber IP (Singapore) Pte.
