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.
