Pluggable fiber optic modules having a receive printed circuit board and a transmit printed circuit board perpendicular with an interface printed circuit board with an edge connection. The edge connection of the interface printed circuit board to plug into and out from an edge connector of a host printed circuit board. A transmitter optoelectronic device is coupled to the transmit printed circuit board. A receiver optoelectronic device is coupled to the receive printed circuit board. The pluggable fiber optic modules may further include a support base, a nose receptacle, and an alignment plate.

Method and apparatus for pluggable fiber optic modules

A multichannel fiber optic module has an electromagnetic shield surrounding high frequency electrical components which is electrically and mechanically coupled to one or more guide rails near edges of a printed circuit board. The one or more guide rails of the printed circuit board include a ground trace on the top and/or bottom surfaces of the printed circuit board. The fiber optic module can be hot inserted into a module cage which has guide rail slots for mating with the guide rails of the fiber optic module. Through the guide rail slots, electromagnetic radiation from the fiber optic module is shunted to a ground plane to which the module cage is coupled on a host chassis ground. Standard singular fiber receptacles are used for the parallel data link modules to allow field cable termination.

Method and apparatus for parallel optical interconnection of fiber optic transmitters, receivers and transceivers

Fiber optic modules having a pull-actuator to unlatch and withdraw (i.e. unplug) it from a cage assembly or a module receptacle. The pull-actuator includes a pull-tab, an arm or push rod, and a catch to couple to a pivot-arm actuator. The pivot-arm actuator pivotally latches to the pull-actuator and to the cage assembly or module receptacle. The pull-actuator makes it easy to de-latch and unplug a fiber optic module. A nose grip is further provided to pull the fiber optic module away from the cage or module receptacle. A belly-to-belly mounting configuration is introduced for the pull-release fiber optic modules.

Multiple board fiber optic modules and methods related thereto. Fiber optic modules include one or more vertical printed circuit boards and/or one or more horizontal printed circuit boards and/or one or more slanted printed circuit boards. The one or more printed circuit boards are parallel to optical axis of one or more optoelectronic devices such as a receiver or transmitter. The one or more printed circuit boards may include a ground plane to minimize electrical cross talk. A shielded housing or cover provides shielding for electromagnetic interference. The base or shielded housing or cover may include a septum to separate the fiber optic modules into a first side and a second side and provide additional shielding to minimize crosstalk. Horizontal, vertical, and NxN arrays of fiber optic channels in fiber optic modules. Fiber optic modules including a mini back plane for edge connecting printed circuit boards.

Pull-action de-latching mechanisms for fiber optic modules

A fiber-optic module having a housing/shielding unit and a module chassis frame having optical, electrical and electro-optical components. The housing/shielding unit functions both as a protective outer housing and an electromagnetic shield. The housing/shielding unit includes forward fingers for a flush mounting in one embodiment and backward fingers for an extended mounting in another embodiment. The fingers can contact a bezel, faceplate or wall of host system to ground the housing/shielding unit to a chassis ground. The module chassis frame may be formed of a conductive material and grounded as well through a host system faceplate or otherwise to the chassis ground. A transmit ground for transmitter components and a receive ground for receiver components are isolated from the chassis ground.

Methods and apparatus for fiber-optic modules with shielded housings/covers with fingers

A fiber optic module for transferring data as pulses of light has an optical element with a first light transducer having a straddle mount lead and a second light transducer having a formed or bent signal lead. A first fiber optic receptacle optically couples to the first light transducer and a second fiber optic receptacle optically couples to a second light. A printed circuit board subassembly includes first and second printed circuit boards with an interconnection therebetween to couple to an electrical connector on the first. The first printed circuit board and second printed circuit boards are aligned so that the straddle mount leads couple to contacts on the first and the formed signal lead couple to contacts on the second. One or more electrical components in the fiber optic module process data for communication using light or photons over one or more optical fibers. An outer housing encloses the optical element subassembly and the printed circuit board subassembly. The electrical connector couples external electrical signals to the electrical components.

A fiber optic module having a push button release to unlatch and withdrawal (i.e. unplug) it from a cage or a module receptacle. A kicker-actuator includes a button, an arm or push rod, and a hook in one embodiment to couple to an actuator. An integrated actuator is also provided with the push button subassembly. Embodiments of a withdrawal tab are also provided to pull the fiber optic module away from the cage or module receptacle. A nose grip is further provided pull the fiber optic module away from the cage or module receptacle. A belly-to-belly mounting configuration is introduced for the push button release fiber optic modules.

Fiber-optic modules with housing/shielding

A method, apparatus, and system to couple photons between optoelectronic devices and small form factor fiber connectors. An optical block includes refraction surfaces to narrow the distance between two or more light transmission paths through the optical block thereby enabling a module to be coupled to closely spaced fiber optic connectors. In one embodiment, light from a first light path through the optical block is refracted in the direction of a second light path through the optical block. Prior to intersecting the second light path, the light from the first light path is refracted again to provide the first light path closer to, but independent of, the second light path.

A fiber-optic module having a housing/shielding unit and a module chassis frame having optical, electrical and electro-optical components. The housing/shielding unit functions both as a protective outer housing and an electromagnetic shield. The housing/shielding unit includes forward fingers and backward fingers. The forward fingers provide an EMI seal around an opening in a bezel, face-plate, backplate, wall, or panel of a host system and thereby can ground the housing/shielding unit to a chassis ground. The backward fingers can contact host tabs of the host system and can also thereby ground the housing/shielding unit to a chassis ground. The module chassis frame may be formed of a conductive material and can be grounded as well through a host system faceplate or otherwise to the chassis ground.
