  • Patent number: 6987932
    Abstract: An optical transceiver is controlled through the use of a monitor optical signal generator and monitor optical signal detector mounted in close physical proximity to the optical signal generator and detector of the transceiver in a housing having a reflective surface. The monitor optical signal generator transmits a reference optical signal that is reflected and directed to the monitor optical signal detector by the reflective surface of the housing. Changes in the reference optical signal detected at the monitor optical signal detector are used for controlling the optical signal generator of the transceiver.

  • Patent number: 6733188
    Abstract: The present invention provides methods for aligning a fiber optic cable with an optical component on a device carrier using a fiber optic lens assembly. One method provides that movement of the lens assembly is fixed with respect to the fiber optic cable. Light is sent through the lens assembly. The fixed lens assembly and fiber optic cable are moved with respect to the device carrier. The light sent though the fixed lens assembly is monitored, and movement of the fixed lens assembly is fixed with respect to the device carrier according to the monitored light. Another method provides that movement of the lens assembly is fixed with respect to the device carrier. Light is sent through the lens assembly. The fixed lens assembly and device carrier are moved with respect to the fiber optic cable. The light sent though the fixed lens assembly is monitored, and movement of the fixed lens assembly is fixed with respect to the fiber optic cable according to the monitored light.

  • Patent number: 6705769
    Abstract: The packaging architecture for a multiple array transceiver using a flexible cable of the present invention provides a 90-degree transition between an optical signal input at a communications chassis bulkhead and an interior board within the communications chassis. The packaging architecture system comprises a forward vertical carrier having an optical converter, a paddle card, a flexible cable operably connected between the forward vertical carrier and the paddle card, and a rearward horizontal I/O block operably connected to the paddle card, the rearward horizontal I/O block oriented about 90 degrees from the forward vertical carrier. The multiple array transceiver makes the 90-degree transition within a narrow gap established by industry and manufacturer standards. The multiple array transceiver further provides cooling through a heat sink.

  • Patent number: 6685364
    Abstract: The enhanced folded flexible cable packaging for use in optical transceivers of the present invention provides a 90 degree transition between an optical signal input/output at a communication chassis bulkhead, and folds 180 degrees around a horizontal heat spreader to provide the capability to wire electrical components to the flexible cable while maintaining the upper surface of the electrical components in close proximity to a heat sink. This allows signals to be processed through a multi-layer flexible cable providing electrical performance without the mechanical stiffness associated with the bends that occur in the package. The multiple array transceiver makes the 90 degree transition within a narrow gap established by industry and manufacturing standards. The multiple array transceiver also provides cooling to the internal electronics through a heat sink attached to the flexible cable and the heat spreader, which concurrently mounts and locates the transceiver to a common host board.
