| 20080226236 | REMOTE GRIP OPTICAL FIBER CONNECTOR - An optical connector for terminating an optical fiber comprises a housing configured to mate with a receptacle and a collar body disposed in the housing. The collar body includes a ferrule securely disposed in an opening of the collar body, the ferrule including a central bore that defines an axis, and a housing portion disposed in a generally central portion of the collar body. The housing portion includes an opening to receive a gripping device to grip an optical fiber. The ferrule is axially moveable independent of the axial movement of the optical fiber and gripping device. The optical connector can be thermally balanced over a temperature range of at least 100° C. | 09-18-2008 |
| 20080292246 | OPTICAL CONNECTOR, OPTICAL FIBER WITH CONNECTOR, OPTICAL FIBER CONNECTING DEVICE, AND OPTICAL FIBER CONNECTION METHOD - A plug-type optical connector is provided with a ferrule and an aligning sleeve member. The aligning sleeve member receives a portion of the ferrule including an abutting end face inside a bore to prevent staining and damage and uses a movable shutter to prevent light emitted through the ferrule from leaking to the outside. The socket type optical connector is provided with a ferrule and a holding section. The optical connector is not provided with an aligning sleeve member and further can hold a coated optical fiber by a holding section behind the ferrule by a radius of curvature of at least a prescribed minimum radius of curvature. Optical loss in the coated optical fiber can be reduced while effectively reducing the external dimensions in the direction of extension of the ferrule at the time of use. An optical fiber connecting device that includes a combination of a pair of optical connectors is also provided to be suitably applied to an optical transmission line laid indoors. | 11-27-2008 |
| 20090071632 | FLEXIBLE HEAT PIPE - A heat pipe for cooling a heat-generating component has a generally planar, sealed flexible body having an evaporator section, a condenser section, and a flexible bellows section. The bellows section is located between the evaporator section and the condenser section along a longitudinal length of the body. A chamber extends from the evaporator section to the condenser section inside the body and contains a working fluid. The bellows section includes internal supports to keep the chamber open during repeated bending of the heat pipe at the bellows section. | 03-19-2009 |
| 20090080839 | OPTICAL CONNECTOR, OPTICAL FIBER WITH CONNECTOR, OPTICAL FIBER CONNECTING DEVICE, AND OPTICAL FIBER CONNECTION METHOD - A plug-type optical connector is provided with a ferrule and an aligning sleeve member. The aligning sleeve member receives a portion of the ferrule including an abutting end face inside a bore to prevent staining and damage and uses a movable shutter to prevent light emitted through the ferrule from leaking to the outside. The socket type optical connector is provided with a ferrule and a holding section. The optical connector is not provided with an aligning sleeve member and further can hold a coated optical fiber by a holding section behind the ferrule by a radius of curvature of at least a prescribed minimum radius of curvature. Optical loss in the coated optical fiber can be reduced while effectively reducing the external dimensions in the direction of extension of the ferrule at the time of use. An optical fiber connecting device that includes a combination of a pair of optical connectors is also provided to be suitably applied to an optical transmission line laid indoors. | 03-26-2009 |
| 20100029180 | OPTICAL FIBER POLISHING APPARATUS AND METHOD - A polishing apparatus is provided for polishing an optical fiber connector. The optical fiber connector includes a connector housing and a ferrule. The polishing apparatus includes a mount to receive and hold the optical connector and a base to support the mount. The base further includes a dispenser portion. The polishing apparatus further includes a polishing strip dispensable by the dispensing portion of the base. The polishing strip has a portion thereof extending through a passageway formed in the mount, where a first surface of the polishing strip is disposed proximate to an end face of the ferrule of the optical connector disposed in the mount. In an exemplary aspect, the polishing strip comprises one or more polishing media disposed on a backing material. | 02-04-2010 |
| 20100098381 | REMOTE GRIP OPTICAL FIBER CONNECTOR - An optical fiber connector comprises an outer housing configured to mate with a receptacle and a collar body disposed in the outer housing. The collar body receives and secures a ferrule in a first portion of the collar body. The ferrule includes a central bore that defines an axis. The ferrule further includes a fiber stub disposed in a portion of the central bore, the fiber stub comprising a first optical fiber having a first end proximate to an end face of the ferrule and a prepared second end terminating within the ferrule. The collar body further includes a second portion that includes a housing portion to house a gripping device that grips a second optical fiber. | 04-22-2010 |
| 20100270350 | BLADELESS OPTICAL FIBER CLEAVER AND METHOD - A bladeless optical fiber cleaver is provided for cleaving an optical fiber connector in a straightforward manner. The bladeless optical fiber cleaver includes a generally planar body that includes a first body portion and a second body portion pivotably coupled to each other, where the second body portion is movable with respect to the first body portion. The fiber cleaver includes a mechanism to create a strain force in a stripped portion of the optical fiber, where the stripped portion under strain is exposed to receive contact from a flexible abrasive material, the flexible abrasive material introducing a flaw in the optical fiber where the cleave takes place. | 10-28-2010 |
| 20100316344 | ASSEMBLY TOOL AND OPTICAL CONNECTOR ASSEMBLY METHOD - An assembly tool for installing an optical fiber in an optical connector includes a base and a protrusion setting station. The base includes a connector mount disposed in the base. The connector mount can be configured to receive and secure the optical connector on the base where the connector has a housing and a connector ferrule. The protrusion setting station enables the craftsperson to set distance (or protrusion) that a terminal end of the optical fiber extends from an end face of the connector ferrule. The protrusion station includes a light source to illuminate the terminal end of the optical fiber, at least one black body absorber to eliminate unwanted reflected light and a window to visualize the terminal end of the optical fiber protruding from the end face of the connector ferrule. | 12-16-2010 |
| 20110058772 | FLEXIBLE OPTICAL COUPLING - An optical fiber coupling device, comprises a coupling assembly that includes a first ferrule and a second ferrule and an optical fiber having a first end mounted in the first ferrule and a second end mounted in the second ferrule. The first ferrule is disposed in an axial bore of a first barrel and the second ferrule is disposed in an axial bore of a second barrel. The coupling assembly is disposable in a coupling housing configured to receive at least two optical fiber connectors. | 03-10-2011 |
