| 20110235975 | OPTOCOUPLER WITH LIGHT GUIDE DEFINING ELEMENT - An optocoupler with a light guide defining element is presented. The light guide defining element has at least one cavity configured to define the shape of the light guide formed by a transparent encapsulant encapsulating the optical transmitter and receiver dies. The transparent encapsulant in liquid form may be injected into the cavity prior to a curing process to harden the encapsulant into a light guide with a predetermined shape. The cavity of the light guide element may be defined by a reflective surface having micro-optics formed thereon. A multichannel optocoupler with multiple transmitter and/or receiver dies having such light guide defining element is also presented. The light guide defining element may have a single cavity enveloping all the optical transmitter or receiver dies, or a multiple cavities by having a pair of transmitter and receiver dies inside each cavity. | 2011-09-29 |
| 20110235976 | Fiber connector and adapter - Fiberoptic connector and adapter assembly includes a fiberoptic connector received within an adapter. The connector has a cover on the connector housing. The cover pivots between open and closed positions to expose or cover, respectively, a optical fiber contained within the connector. Longitudinal guides of the connector are received cooperating with longitudinal guides of the adapter to direct the connector into the adapter in a prescribed alignment. A cam pin is carried on the adapter to engage a cam pin receiving slot on the cover to urge the cover to the open position as the connector is inserted into the adapter. | 2011-09-29 |
