  • Patent number: 11953741
    Abstract: An example optoelectronic module includes a housing that extends between a first end and an opposite second end. The optoelectronic module includes a printed circuit board (“PCB”) with an electrical connector at an end thereof, a transmitter electrically coupled to the PCB, a receiver electrically coupled to the PCB, and a receiving member including a plurality of ports each configured to receive a respective one of a plurality of fiber optic cables. In one aspect, the receiving member includes a plurality of deformable retaining members configured to be positioned in corresponding receptacles of the housing member in an arrangement structured to limit movement of the receiving member. In another aspect, the module also includes a plurality of fiber optic cable receptacles and a receptacle retaining member is positioned between the housing and the receptacles and limits movement of the receptacles in the housing.

  • Patent number: 11817854
    Abstract: A technique for powering gate drivers in a half-bridge configuration uses a single external power supply to power each gate driver. A single on-chip regulator regulates the positive turn-on voltage for each switch. The regulator overhead, is also used as the negative voltage for turn-off, thus transferring the low-frequency variation of the external power supply to the negative turn-off voltage. Accordingly, a single on-chip regulator generates both the positive turn-on voltage and the negative turn-off voltage. In at least one embodiment, reuse of the switch turn-off current further reduces on-chip power dissipation. The on-chip regulator's output filter capacitor discharges during turn-on of the external power switching device. During turn-off, the current that discharges the switch gate capacitance recharges the regulator filter capacitor.

  • Patent number: 10222556
    Abstract: A fiber optic connector may include a body, a first fiber ferrule, and a second fiber ferrule. The first fiber ferrule may extend in a length direction of the body from a module-side end of the body. The second fiber ferrule may extend in the length direction of the body from the module-side end of the body and may be spaced apart from the first fiber ferrule in a width direction of the body. A maximum width in the width direction of a portion of the body configured to be received in a port of an optoelectronic communication module may be less than half a width of a fiber-side end of the optoelectronic communication module.

  • Patent number: 8717770
    Abstract: Latching mechanisms for pluggable electronic devices. In one example embodiment, a latching mechanism includes a driver and a follower. The driver is configured to rotate about an axis between a latched positioned and an unlatched position. The follower is operably connected to the driver and configured to slide axially along an electronic device toward the driver as the driver is rotated from the unlatched position to the latched position and slide axially along the electronic device away from the driver as the driver is rotated from the latched position to the unlatched position.
