Topic: high speed photodetector

Co-packaged optics is changing the definition of a receiver. In traditional pluggable modules, the optical engine sits on the faceplate and high-speed electrical signals travel several inches across the PCB to reach the switch ASIC. Those long copper traces waste power, add loss, and force expensive retimers or DSP blocks into the link. CPO optics? removes that distance by placing the optical engine on the same substrate as the switching chip, shrinking the electrical path to the millimeter scal...
