Abstract
In one example embodiment, an electromagnetic radiation (EMR) shield includes a central portion, an opening defined in the central portion, a wing attached to and extending outward from the central portion, and a protrusion defined in the wing. The perimeter of the EMR shield is approximately the same size and shape as that of a portion of an associated optical subassembly (OSA).
Claims18
An electromagnetic radiation (EMR) shield comprising:
- a central portion;
- an opening defined in the central portion;
- a wing attached to and extending outward from the central portion;
- and
- a protrusion defined in the wing;
- wherein a perimeter of the EMR shield is approximately the same size and shape as that of a portion of an associated optical subassembly (OSA), wherein the opening has a diameter that is smaller than a diameter of a fiber port.
3 more elements
An OSA comprising:
- a body comprising:
- a receptacle that defines a connector port;
- a flange extending from the receptacle;
- a first barrel extending from the flange and defining a lens;
- a second barrel defined within the connector port that defines a fiber port configured to receive an optical fiber, the fiber port having a diameter;
- and
- an EMR shield at least partially embedded in the body, the EMR shield comprising:
- a central portion;
- a wing attached to and extending outward from the central portion;
- a protrusion connected to the wing and/or the central portion that extends outside the body;
- and
- an opening defined in the central portion, wherein the opening has a diameter that is smaller than the diameter of the fiber port.
9 more elements
An optoelectronic device comprising:
- a faceplate;
- a printed circuit board (PCB);
- and
- an OSA attached to the faceplate and electrically connected to the PCB, the OSA comprising:
- a body comprising:
- a receptacle that defines a connector port;
- a flange extending from the receptacle;
- a first barrel extending from the flange and defining a lens;
- a second barrel defined within the connector port that defines a fiber port configured to received an optical fiber, the fiber port having a diameter;
- and
- an EMR shield at least partially embedded in the body, the EMR shield comprising:
- a central portion;
- a wing attached to and extending outward from the central portion;
- a protrusion connected to the wing and/or the central portion that extends outside the body and is in electrical contact with the faceplate;
- and
- an opening defined in the central portion, wherein the opening has a diameter that is smaller than the diameter of the fiber port.
