  • Patent number: 9618711
    Abstract: An apparatus for forming a transceiver interface includes an fiber optic ferrule and an optical transceiver component. The fiber optic ferrule engages a mating plane of a lens array in the optical transceiver component. The engagement of the two components may be removable rather than fixed. The fiber optic ferrule also engages a mechanical interface to account for three degrees of freedom, while the engagement of the mating surfaces account for another three degrees of freedom.

  • Patent number: 9500824
    Abstract: To increase the protection of a fiber optic connector system from EMI, apertures in the system must be as small as possible. To reduce the size of apertures in the system, the openings are minimized by using electrically conductive fiber optic connector parts, including a connector housing, a fiber optic ferrule disposed within the electrically conductive connector housing, and an electrically conductive heat-shrink attachment securable to the connector housing. An electrically conductive heat shrink may be attached to the heat-shrink attachment to provide more protection.
