Classification: CPC H  G | IPC G  H

Claim 16:
17. A switch system comprising:
an optical transceiver assembly;
wherein the optical transceiver assembly is connected to a switch ASIC;
wherein the switch ASIC switches electrical signals;
wherein the optical transceiver assembly includes a layer stack; and
wherein the layer stack comprises:
a transceiver chip,
optical beam forming layers, which each layer includes lenses or lens arrays etched into the layers' material and which are configured to form an optical beam,
a pluggable optical interface including mechanical guide pins, and
an optical imaging system expanding and collimating the optical beam;

wherein a digital signal processing chip of the optical transceiver assembly is located next to the transceiver chip on a primary high-speed substrate,
wherein the primary high-speed substrate is electrically and mechanically connected to a second high-speed substrate;
wherein the switch ASIC is electrically and mechanically connected to the second high-speed substrate;
wherein a distance from the digital signal processing chip to the switch ASIC is smaller than a distance from the transceiver chip to the switch ASIC;
wherein a pluggable optical connector of the optical transceiver assembly comprises a first heat spreader, wherein the first heat spreader is integral to and movable together with the pluggable connector; and
wherein the heat spreader comprises an overlap section, wherein the overlap section overlaps with both the digital signal processing chip and the transceiver chip when the pluggable optical connector is plugged in;
wherein the digital signal processing chip and the transceiver chip are sandwiched between the first heat spreader of the pluggable optical connector and the primary high-speed substrate when the pluggable optical connector is plugged to a transceiver receptacle.
