An example method of assembling an optoelectronic assembly may include aligning a receptacle with a sleeve that may have a radial flange and with a ferrule that may have a light propagation axis. The method may include axially displacing one or more of the receptacle, the sleeve, and the ferrule such that the receptacle may be positioned at least partially within the sleeve and may at least partially surround the ferrule. The method may include aligning a fiber stub that may have a fiber stub pigtail and a fiber stub flange with the receptacle. The method may include axially displacing one or both of the fiber stub and the receptacle such that the fiber stub may be positioned in close proximity with the ferrule. The method may include coupling the sleeve via the radial flange and the fiber stub via the fiber stub flange with a retention device.

Retention device for optoelectronic connections

An alignment connector for an optoelectronic module can include: a front end having a first gripper arm and a second gripper arm with an alignment connector aperture between the first gripper arm and the second gripper arm; a base having a bottom surface and a receptacle surface; the back end having a first back wall and a second back wall with a back gap therebetween; and a ferrule receptacle extending to a medial region where the alignment connector aperture extends from, and including a portion of the receptacle surface, the ferrule receptacle being defined by a first side wall having a first latch arm and a second side wall having a second latch arm. The alignment connector can be included in a module with a bail or pull-tab. Alternatively, the first gripper arm and second gripper arm can be mounted directly to a module housing.

Small footprint parallel optics transceivers

A module mount interposer may include one or more fastener receivers configured to mechanically couple with one or more fasteners so as to mechanically and electrically couple a module to the interposer. The module mount interposer may also include a core configured to electrically couple with the module, wherein each of the fastener receivers are mechanically coupled to the core. The module mount interposer may additionally include a solder layer electrically coupled to the core and configured to electrically couple with a printed circuit board (PCB) so as to provide an electrical signal from the module to the PCB and to provide an electrical signal from the PCB to the module.

Module mount interposer

An example optoelectronic module may include an optical subassembly (OSA), an optical port block, a housing, and a holder. The OSA may be configured to convert between optical and electrical signals. The optical port block may be attached to the OSA and may be configured to optically align a fiber optic cable with the OSA. The housing may be configured to substantially enclose the OSA and the optical port block. The holder may be configured to couple the OSA and the optical port block to the housing. The holder may be detachably coupled to the optical port block and fixedly coupled to the housing.

Optical subassembly with detachably-coupling holder

A ferrule-to-lens latch mechanism includes a cover movable with respect to a housing of an optical assembly between an open position in which a cavity defined by the housing is visible and a closed position in which the cavity is covered by the cover. A lens is positioned in the cavity and has one or more guide pins which are visible when the cover is in the open position prior to mating a ferrule to the lens. A spring clip coupled to the housing and positioned in the cavity is configured to allow insertion and removal of the ferrule from the cavity when the cover is in the open position and may bias the ferrule against the lens when the ferrule is mated to the lens. When the ferrule is mated to the lens, the cover may cooperate with the spring clip to inhibit removal of the ferrule.

Ferrule-to-lens latch mechanism

In an embodiment, an optoelectronic module includes a printed circuit board (PCB) and a lens block. The printed circuit board (PCB) includes at least one of an optical transmitting or receiving array. The lens block may be configured for directly coupling light between one of the optical transmitting or receiving array to optical fibers in an optical cable. A method may include directly coupling light between one of an optical transmitting or receiving array and a lens block, and further coupling the light through the lens block directly to an optical fiber of an optical cable externally coupled to the optoelectronic module.

Optical module with integrated lens

An embodiment includes a cable connector that includes a connector housing, a fiber support structure, and a latch structure. The connector housing defines a housing cavity. The fiber support structure is attached to the connector housing and extends therefrom in a first direction. The fiber support structure defines a fiber cavity configured to receive a fiber subassembly. The latch structure is attached to the connector housing at a first end and extends therefrom in the first direction. The latch structure is separated in a second direction from the fiber support structure and includes a ramped surface at a second end. The ramped surface displaces the latch structure in a direction opposite the second direction in response to a force in a direction opposite the first direction and does not include a release structure configured to disengage the latch structure from latch tabs of a communication module.

Cable connector

A latch may include a follower and a driver. The follower may include a follower opening configured to receive a post of a housing. The driver may include a driver opening configured to receive the post of the housing such that the driver is selectively rotatable relative to the post. The driver may further include an interfacing finger positioned to be received by the follower opening. The interfacing finger may be configured to urge the follower to slidingly move relative to the housing as the driver is rotated relative to the post.

Latch mechanism for communication module

An example embodiment includes a latching mechanism configured to selectively secure a communication module to a receptacle of a host device. The latching mechanism includes a latch, a cam, and a latch release. The latch includes a latch hook and a latch protrusion. The cam is mechanically coupled to the latch release. The cam is positioned with respect to the latch such that an activation force applied to the latch release translates the cam to contact the latch protrusion and displace the latch hook.
