| 20150147036 | FIBER OPTIC PLUG HAVING AN ARTICULATED FORCE STRUCTURE TO INHIBIT ANGULAR FERRULE BIASING DURING INSERTION INTO AN OPTICAL RECEPTACLE, AND RELATED ASSEMBLIES AND METHODS - Fiber optic plug connectors having an articulated force structure to inhibit angular ferrule biasing are disclosed. An articulated force structure is provided in the fiber optic plugs to apply a forward force to a ferrule of the fiber optic plug, to dispose the fiber optic plug ferrule in close proximity to an optical interface of the optical receptacle to provide an optical connection therebetween. By the articulating force structure providing an articulating forward force to the fiber optic plug ferrule, the ferrule is able to angularly rotate to inhibit angular biasing applied to the fiber optic plug ferrule as a result of inserting the fiber optic plug into an optical receptacle. The articulating force structure providing an articulating forward force to the fiber optic plug ferrule facilitates alignment of the ferrule with the optical receptacle to preserve optical performance. | 05-28-2015 |
| 20150346434 | FABRICATION METHOD FOR OPTICAL CONNECTOR AND OPTICAL CONNECTOR - A fabrication method for an optical connector, includes: inserting an optical waveguide sheet, in a direction of an optical path of the optical waveguide sheet, into an insertion hole of an optical connector including lenses disposed in a juxtaposed relationship on a first end face of the optical connector, the insertion hole extending from a second end face of the optical connector at an opposite side to the first end face toward the lenses; and performing first adjustment of adjusting a position of a tip end of the optical path with respect to the lenses by pressing a side end portion of the optical waveguide sheet inserted in the insertion hole from at least one of sides of a first direction along a disposition direction of the lenses, through a first hole portion that is provided in the optical connector and extends to the insertion hole. | 12-03-2015 |
| 20160085034 | FIBER OPTIC CONNECTORS AND INTERFACES FOR FIBER OPTIC CONNECTIVITY THROUGH DEVICE DISPLAY SURFACE, AND RELATED COMPONENTS, SYSTEMS AND METHODS - A fiber optic connection system is disclosed for optically connecting a fiber optic connector to an internal optical interface of a device through a display surface of the device. Connecting the connector to the device causes a display alignment feature of the connector to be retained against the display surface of the device. This causes a connector optical interface in the connector to optically connect to a device optical interface through the display surface of the device when the connector is connected with the device. One benefit of this arrangement is that a device, such as a smartphone or other small form-factor device for example, may include optical communication hardware that leverages the excellent clarity and flatness of the display surface, such as a display glass for example, to form and maintain a strong fiber optic connection between the connector and the device. | 03-24-2016 |
| 20160091672 | PRECISION ALIGNMENT OF OPTICAL FIBER ENDS ALONG RESPECTIVE OPTICAL PATHWAYS IN A MULTI-OPTICAL FIBER CONNECTOR MODULE, AND METHODS - An MF connector module is provided that positions the fiber end portions relative to respective V-grooves of the module in such a way that the fiber end portions can be bent, and thereby loaded, by a predetermined amount when the fiber end portions are being installed in the respective V-grooves. The bending of the fiber end portions ensures that the optical axes of at least the tips of the fiber end portions are parallel to the optical axes of the respective V-grooves. The loading of the fiber end portions caused by the bending ensures that significant lengths of the fiber end portions are tangent to and in contact with the inner walls of the respective V-grooves. This tangential contact between the fiber end portions and the inner walls of the V-grooves causes the fiber end faces to be precisely aligned with the respective optical axes of the MF connector module. | 03-31-2016 |

| 20160161678 | EXPANDED BEAM FIBER OPTIC CONENCTOR, AND CABLE ASSEMBLY, AND METHODS FOR MANUFACTURING - A fiber optic cable and connector assembly is disclosed. In one aspect, the assembly includes a cable optical fiber, an optical fiber stub and a beam expanding fiber segment optically coupled between the cable optical fiber and the optical fiber stub. The optical fiber stub has a constant mode field diameter along its length and has a larger mode field diameter than the cable optical fiber. In another aspect, a fiber optic cable and connector assembly includes a fiber optic connector mounted at the end of a fiber optic cable. The fiber optic connector includes a ferrule assembly including an expanded beam fiber segment supported within the ferrule. The expanded beam fiber segment can be constructed such that the expanded beam fiber segment is polished first and then cleaved to an exact pitch length. The expanded beam fiber segment can be fusion spliced to a single mode optical fiber at a splice location behind the ferrule. | 06-09-2016 |
| 20160187593 | FIBER OPTIC CONNECTORS EMPLOYING MOVEABLE OPTICAL INTERFACES WITH FIBER PROTECTION FEATURES AND RELATED COMPONENTS AND METHODS - Embodiments disclosed herein include fiber optic connectors employing a movable optical interface connected by optical fibers to a fiber optic cable, components and methods. In one embodiment, the movable optical interface moves between an extended position for cleaning by the user of the movable optical interface and a retracted position to optically connect the fiber optic connector to an optical device in a mechanically-secure manner. Because the fiber optic cable employs the movable optical interfaces, embodiments described herein involve one or more fiber protection features to prevent optical fiber attenuation and/or damage to the end portions of the optical fibers. | 06-30-2016 |
