  • Fiber optic cable assembly for optical transceiver
    Patent number: 8718479
    Abstract: Disclosed is an optical floating sub-assembly, comprising a thermally conductive non rigid substance between the heat sink carrier and external casing, to minimize mechanical stress on the optical assembly. Also disclosed is a printed circuit board as an electrical interface, comprising two modules capable of converting an electrical signal to an optical signal, transmitting the optical signal and then converting the optical signal back to an electrical signal. Also disclosed is an optical assembly, comprising a heat sink with mechanical features for optical alignment.
    Type: Grant

  • OPTO-ELECTRICAL ASSEMBLIES AND ASSOCIATED APPARATUS AND METHODS
    Publication number: 20110089438
    Abstract: Provided is a method of providing an opto-electrical assembly. The method comprises attaching a second electrical element to a carrier using a second attachment region at a second attaching temperature. The second attaching temperature is associated with the melting temperature of the second attachment region, such as the melting temperature of solder or the like. The carrier already comprises a first opto-electrical element having been attached to the carrier using a first attachment region at a first attaching temperature, whereby the first attaching temperature is associated with the melting temperature of the first attachment region. The method is provided such that the second attachment region has a lower melting temperature than the first attachment region such that the second attaching temperature is lower than the first attaching temperature.
