  • Patent number: 6682231
    Abstract: An optical subassembly for aligning an optical fiber with a light emitting device includes a fiber optic stub mounted in a ferrule and a v-groove device coupled to the ferule with a loose end of the fiber optic stub lying in the v-groove device. The other end of the fiber optic stub is polished. According to methods contemplated by the invention, the ferrule is mounted in a ring which is welded to a light emitting subassembly. The unpolished loose end of the fiber optic stub self-aligns with a mating fiber in the v-groove device. According to the presently preferred embodiment, the v-groove device is provided with s-bends which aid in self-alignment between the loose fibers.

  • Patent number: 6494623
    Abstract: A release mechanism for manually securing a pluggable fiber optic transceiver to a cage mounted on a host circuit board. The transceiver is secured to the cage by a boss extending from a lower wall of the transceiver housing that is received in an opening formed in a resilient transceiver latch of the cage. The release mechanism includes a locking mechanism including a shaft rotatably connected to the transceiver body, a lever extending from a front end of the transceiver body and connected to a first end of the shaft, and a cam mounted at a rear end of the shaft adjacent to the locking mechanism. When the lever is manually rotated, the cam pushes the transceiver latch away from the boss, thereby allowing the transceiver to be pulled from the cage by the lever.
