20090052836 | Optical Fiber Data Link - A data link for transmitting data between first and second optically active devices, such as in articulated electronic devices. A coupling unit is mounted above each optically active device. Each coupling unit has a convexly tapered well extending between a top surface and a bottom surface, with a larger opening in the top surface and a smaller opening at the bottom surface. The tapered well receives one end of the optical fiber and aligns the end with the corresponding optically active device. The smaller opening of the well may have a circular cross-section or a keyhole cross-section. A groove may be disposed near a top surface of each coupling unit, with the groove extending between the tapered well and a sidewall of the coupling unit. A segment of the optical fiber disposed near an end curves along the contour of the convexly tapered sidewalls when the optical fiber is inserted into the groove. A pair of opposed lips retain the optical fiber in the groove. | 02-26-2009 |
20090154884 | Multifiber MT-Type Connector and Ferrule Comprising V-Groove Lens Array and Method of Manufacture - A fiber optic ferrule, preferably an MT-type ferrule, and connector design is provided that includes a unitary v-groove lens array (v-lens). The v-lens comprises a plurality of lenses and corresponding plurality of open v-grooves to align optical fibers with the plurality of lenses. Because the v-groove lens array is a unitary structure, high precision manufacturing is required for only the v-groove lens array, and not for other components forming the ferrule. A housing holds the v-groove lens array and preferably comprises a cantilever configured to retain the optical fibers substantially within their corresponding v-grooves. An opening in the housing allows an adhesive to be placed in contact with the housing, optical fibers and v-groove lens array thereby retaining the various components in a fixed relationship. A fiber optic connector may include the fiber optic ferrule in accordance with the present invention disposed within a suitable connector housing. | 06-18-2009 |
