  • Compact optical sub-assembly with integrated flexible circuit
    Publication number: 20050175299
    Abstract: The invention relates to an optical sub-assembly package for use in receiver optical sub-assemblies or transmitter optical sub-assemblies in which the electrical connections between the transducer chip, e.g. photo-detector or light source, and the device printed circuit board is made by a single flexible circuit conductor extending through the wall of the package. The package is comprised of a housing and a stiffening plate, which encloses and end of the housing and forms a mechanical support for an end of the flexible circuit conductor.

  • Heat sink tab for optical sub-assembly
    Publication number: 20050162761
    Abstract: The present invention relates to a heat sinking tab for dissipating heat directly from an optical sub-assembly (OSA) to a transceiver housing, within which the optical sub-assembly is located. The heat sinking tab includes a mounting plate for mounting on the rear end of a transistor outline (TO) can, and a finger for extending into contact or close proximity to the transceiver housing. The mounting plate also provides a stiffening plate for flexible conductors used to connect the OSA leads to a transceiver printed circuit board (PCB).
