| 20120301082 | OPTICAL CONNECTOR THAT COMPENSATES FOR LONGITUDINAL SHIFTING OF OPTIAL FIBER CORE RELATIVE TO A HOUSING OF THE CONNECTOR, AND A METHOD - An optical connector is provided having a housing with a cavity formed therein through which an optical fiber passes. Within the cavity, a slightly bent, unjacketed portion of the core of the optical fiber is disposed. If conditions are such that pistoning of the core begins to occur, the slightly bent, unjacketed portion of the core straightens, thereby causing the end of the core to remain substantially flush with the end of the ferrule of the connector housing. In this way, the pistoning effect at the end of the fiber is prevented and optical losses associated with the occurrence of the pistoning effect are avoided. | 11-29-2012 |
| 20120155808 | FIBER OPTIC CONNECTORS - Fiber optic connectors for use in connecting and aligning two optical fibers. In one example embodiment, a fiber optic connector includes a body, a cylindrical split sleeve at least partially positioned within the body, and a shell at least partially positioned within the body and surrounding the split sleeve. The body defines an internal port and an external port. The split sleeve defines a slot along the length of the split sleeve and has first and second open ends. The first end is configured to receive and grip a ferrule of an internal optical fiber and the second end is configured to receive and grip a ferrule of an external optical fiber. The portion of the shell surrounding the first end has a greater inside clearance than the portion of the shell surrounding the second end. | 06-21-2012 |
| 20110091159 | Push-Pull Fiber Optic Connectors and Methods for Making the Same - Push-pull fiber optic connectors and cable assemblies having a latch that is actuated by a cam surface are disclosed. The fiber optic connectors include a ferrule and a housing having the latch. A shroud fits over a portion of the housing and allows the craft to grab the shroud and push the shroud and hence the fiber optic connector into a suitable adapter or the like. Likewise, the craft can grab the shroud and pull on the same to remove the fiber optic connector out of the adapter or the like. The cam surface is disposed on a decoupling member, wherein the decoupling member is attached to the shroud so the components can move together. Methods of making the push-pull fiber optic connector are also disclosed. | 04-21-2011 |
| 20100247040 | FERRULE CONNECTING STRUCTURE - A ferrule connecting structure for optically connecting a pair of fibers which are provided in a pair of ferrules, respectively, the ferrule connecting structure comprises: a first holding portion which holds the pair of ferrules; an peripheral portion which is provided on the pair of ferrules and which includes a plurality of groove portions; a second holding portion which is fit in the groove portion so as to hold the ferrule in a particular rotating position about an axis of the optical fiber; a third holding portion which is detachably attached to the first holding portion so as to press the first holding portion in a direction intersecting with the axis; and a fourth holding portion which presses the pair of ferrules in a direction in which the end faces of the pair of ferrules are opposed to each other. | 09-30-2010 |
| 20120128304 | MATING OF OPTICAL FIBERS HAVING ANGLED END FACES - A method for mating optical fibers, a fiber optic connector, and a fiber optic subassembly are provided in which mating fibers have angled end faces joined by index matching fluid, but in which the angled end faces of the fibers are positioned relative to one another in rotationally misaligned relationship. Applicants discovered unexpectedly that optical fibers can be spliced, to provide satisfactory optical connections, without the need for matched cleaves, and without the need for precise rotational alignment of the cleaves, provided that angled end faces are provided on both the launch and receive fibers and that index matching gel is provided between the angled end faces. Thus, the fibers are mated in positions other than in the precise rotationally aligned position previously believed essential to adequate optical performance. Angled end faces may be positioned less than 165 degrees out of phase. | 05-24-2012 |
| 20100272397 | OPTICAL CONNECTOR - Provided is an optical connector in which a through-hole of a housing is opened in a side surface of the housing and a ferrule can be mounted to the housing from an opening portion formed in the side surface of the housing. Thus, it is unnecessary to constitute the housing by a plurality of components. Consequently, reduction in the numbers of components and assembly steps and reduction in cost can be achieved. | 10-28-2010 |
| 20120082416 | OPTICAL CONNECTOR, CONNECTOR ADAPTER, OPTICAL FIBER LINE, AND OPTICAL COMMUNICATION SYSTEM - There are provided an optical connector having one or more protruding portions protruding and one or more recessed portions depressed relative to a reference plane corresponding to a reference face of a coupling of a standard optical connector in a connecting end face of a coupling into which a housing receiving a ferrule is inserted, a connector adapter to which the optical connector can be inserted and coupled, an optical fiber line using the optical connector and the connector adapter to connect optical fibers, and an optical communication system. | 04-05-2012 |
| 20120275748 | OPTICAL CONNECTOR - The present invention relates to an optical connector including, a ferrule within which an integrated optical fiber is fixed, a clamp portion disposed at a rear of the ferrule, the clamp portion comprising: a base component and a lid component facing the based component, where the base component and the lid component together are configured to clamp an end portion of the integrated optical fiber and an end portion of a naked optical fiber abutting the end portion of the integrated optical fiber, and a naked optical fiber guide portion disposed at a rear of the clamp portion, where the naked optical fiber guide portion comprises a through hole through which the naked optical fiber can be inserted, and that guides the naked optical fiber to the clamp portion by the through hole. | 11-01-2012 |
