An optimized ground (GND) network connection is provided between a Quad Small Form-factor Pluggable (QSFP) connector and a printed circuit board (PCB). The optimized GND network creates a 'GND Island' around the signal pads by adding GND cage around the signal pads (at the empty corridor and in front of QSFP pads) and GND TH (ground through hole) vias from both sides of signal pads (at the empty corridor and in front of QSFP pads).

Module compliance boards for quad small form-factor pluggable (QSFP) devices

An apparatus includes a connector that connects to optical fibers for connecting first and second optical signals to the apparatus. A first optical ferrule is mounted perpendicularly to the connector, and transfers the first optical signals between the connector and first optical transducers mounted on a first substrate, via first holes formed in the first substrate. A second optical ferrule is mounted perpendicularly to the connector, and transfers the second optical signals between the connector and second optical transducers mounted on a second substrate, via second holes formed in the second substrate. A light rotation module bends and transfers the first and second optical signals between the connector and the first and second ferrules. One or more lenses are mounted between the first ferrule and the first holes, so as to couple the first optical signals via the first holes between the first ferrule and the first optical transducers.

Optical interface and splitter with micro-lens array

An optical interface module includes a single flexible Printed Circuit Board (PCB) including conductive traces. An electrical connector, one or more opto-electronic transducers and ancillary circuitry are disposed on the flexible PCB. The electrical connector is configured to mate with a corresponding connector on a substrate. The opto-electronic transducers are configured to be coupled to optical fibers carrying optical signals. The ancillary circuitry is coupled by the traces to the opto-electronic transducers and the electrical connector so as to convey electrical signals corresponding to the optical signals between the opto-electronic transducers and the electrical connector.

Optical module fabricated on folded printed circuit board

An apparatus includes an optical Input/Output (I/O) connector, which has a central axis that is mounted in a plane and which is configured to connect to external optical fibers for transferring input optical signals to the apparatus and output optical signals from the apparatus. A first optical ferrule is mounted perpendicularly to the optical I/O connector in the plane, and is configured to transfer the input optical signals from the optical I/O connector to respective optical detectors. A second optical ferrule is mounted perpendicularly to the optical I/O connector in the plane, and is configured to transfer the output optical signals from respective optical emitters to the optical connector. A light rotation module is configured to bend and transfer the input and output optical signals between the optical I/O connector and the perpendicularly-mounted first and second optical ferrules.
