Heat sink cover

An apparatus for dissipating heat from a photonic transceiver module. The apparatus includes a top-plate member disposed in a length direction of a package for the photonic transceiver module. The apparatus further includes multiple fins formed on the top-plate member along the length direction from a backend position to a frontend position except at least one fin with a shorter length, forming an elongated void from the backend position to one backend of the at least one fin. Additionally, the apparatus includes a cover member disposed over the multiple fins with a horizontal sheet, two vertical side sheets, and a flange bent vertically from a middle portion of backend of the horizontal sheet. Furthermore, the apparatus includes a spring loaded in the elongated void between the flange and the one backend of the at least one fin to minimize an air gap at the backend of the horizontal sheet.

Apparatus and method for thermal dissipation of photonic transceiving module

One embodiment includes a connector comprising a connector housing, a ferrule, and a crimp ring. The connector housing has inner and outer surfaces extending between forward and rear ends of the connector housing. The inner surfaces defined a passageway extending lengthwise between the forward and rear ends. The connector housing includes at least one protrusion formed on one of the outer surfaces that is configured to engage a corresponding connector engaging structure of an alignment guide to secure the connector housing within the alignment guide. The ferrule is configured to mount upon end portions of a plurality of optical fibers of a multi-fiber communication cable. The ferrule is disposed partially within the passageway. The crimp ring encompasses the rear end of the connector housing and is configured to secure the connector to the multi-fiber communication cable.

Various embodiments for providing removable and pluggable opto-electronic modules for illumination and imaging for endoscopy or borescopy are provided for use with portable display devices. Generally, various medical or industrial devices can include one or more solid state or other compact electro-optic illuminating elements located thereon. Additionally, such opto-electronic modules may include illuminating optics, imaging optics, and/or image capture devices. The illuminating elements may have different wavelengths and can be time-synchronized with an image sensor to illuminate an object for imaging or detecting purpose or other conditioning purpose. The removable opto-electronic modules may be plugged in on the exterior surface of a device, inside the device, deployably coupled to the distal end of the device, or otherwise disposed on the device.

Pluggable vision module and portable display for endoscopy

Various embodiments for providing removable, pluggable and disposable opto-electronic modules for illumination and imaging for endoscopy or borescopy are provided for use with portable display devices. Generally, various medical or industrial devices can include one or more solid state or other compact electro-optic illuminating elements located thereon. Additionally, such opto-electronic modules may include illuminating optics, imaging optics, and/or image capture devices. The illuminating elements may have different wavelengths and can be time-synchronized with an image sensor to illuminate an object for imaging or detecting purpose or other conditioning purpose. The removable opto-electronic modules may be plugged onto the exterior surface of another medical device, deployably coupled to the distal end of the device, or otherwise disposed on the device.

Disposable endoscope and portable display

Latching mechanisms for electronic modules. In one example embodiment, a latching mechanism for an electronic module includes a latch, a latch return spring, and a release slide. The latch is configured to rotate between a latched position and an unlatched position. The latch includes a latch arm on a first end of the latch and an engagement pin on a second end of the latch. The latch return spring is configured to bias the latch in the latched position. The release slide includes a slide ramp. The slide ramp is configured to engage the latch arm as the release slide is slid away from the engagement pin, which causes the latch to rotate from the latched position to the unlatched position.

The principles of the present invention provide for a plastic ROSA that has a metallic EMI shroud covering a portion of the plastic ROSA. The combination of the plastic ROSA and the EMI shroud provides the unexpected result of having EMI shielding substantially similar to a metal ROSA.

EMI shroud for a plastic optical subassembly

Electromagnetic radiation (EMR) containment assemblies for use in optoelectronic modules. In one example embodiment, an EMR containment assembly includes an EMR shield and a mounting spring plate attached to the EMR shield. The EMR shield includes a first substantially flat body defining at least one edge, a plurality of optical ports defined in the first body; and a plurality of fingers defined along at least one edge of the first body. The fingers are configured to bias against a housing of an optoelectronic module. The mounting spring plate includes a second substantially flat body defining at least one edge, an optical window defined in the second body, and a plurality of leaf springs defined along at least one edge of the second body. The leaf springs are configured to bias against an alignment guide positioned within the optoelectronic module.

In one example, a rotatable top shell is provided for an example optoelectronic device. The rotatable top shell includes a body defining a curved tongue on one end. The tongue is configured to rotate about a complimenting curved mating surface of a bottom shell of the optoelectronic device to allow the body to rotate between an open position and a closed position. The rotatable top shell further includes means for securing the rotatable top shell relative to the bottom shell. The means for securing the rotatable top shell may include one or more of: a plurality of nubs defined along at least one edge of the body, a hole defined in the body for receiving a retention pin of the bottom shell, two sides for being received within a main cavity of the bottom shell, or the like.

Rotatable top shell

In one example embodiment, an optoelectronic module comprises a body, a signal ground, and an OSA. The body is connected to chassis ground and defines a cavity within which one or more components are disposed. The optical subassembly is disposed in the body cavity, has one or more components connected to signal ground, and comprises a header assembly, a housing, and one or more containment structures. The header assembly houses one or more components that generate EMI emissions and includes an optical aperture. The housing includes a port and a barrel. The port defines a fiber receptacle and the barrel defines a cavity that at least partially receives the header assembly. The containment structure(s) at least partially contain the EMI emissions within the OSA.

Electromagnetic interference containment structures

A transceiver module that utilizes a side contact spring portion to ground a shielded cable that is plugged into the transceiver module. In one example embodiment, a transceiver module includes a housing, a jack, and a side contact spring portion. The housing is operative to be electrically connected to chassis ground when the transceiver module is received within a host port. The jack is defined in the housing and operative to receive a shielded plug. The side contact spring portion is substantially implemented within the jack and is configured to be in electrical contact with both the housing and a conductive element of the shielded plug received by the jack such that a chassis ground is established between the housing and the shielded plug and such that a moveable bail pivot lever is able to move without disrupting the electrical contact between the side contact spring portion and the housing and/or the conductive element of the shielded plug.
