1. A switch system comprising:
an optical transceiver assembly connected to a switch ASIC;
wherein a digital signal processing chip of the optical transceiver assembly is located next to a 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.
