  • PLUGGABLE MECHANISM OF OPTICAL TRANSCEIVER
    Publication number: 20180136415
    Abstract: An optical transceiver that optionally exchanges between the bail and the pull-tab for disengaging the optical transceiver with the cage is disclosed. The optical transceiver provides a slider to be assembled with both of the bail and the pull-tab. The slider provides an opening common to the bail and the pull-tab, and a composite opening that includes a portion for the bail and another portion for the pull-tab. The bail, by rotating around the common opening, may induce forward and rearward motions for the slider, while, the pull-tab, by pulling and pushing, may directly cause the forward and rearward motions for the slider through the composite opening.
