3-Second Blueprint (English)

  1. Pluggable transceivers rely on long PCB differential lanes from the switch ASIC, causing skew, latency, and high power draw at AI scale.
  2. Co-Packaged Optics (CPO) mounts optical engines on the same substrate as the switch ASIC, shrinking electrical paths to millimeters.
  3. CPO scales bandwidth past 100 Tbps with lower power, though failed optical engines are harder to swap than front-panel pluggables.

3-Sekunden-Fazit (Deutsch)

  1. Steckbare Transceiver nutzen lange differenzielle Leiterbahnen vom Switch-ASIC, was bei KI-Clustern Skew, Latenz und Strombedarf erhöht.
  2. Co-Packaged Optics (CPO) platziert Optikmodule direkt neben dem Switch-ASIC auf demselben Substrat und verkürzt Pfade auf Millimeter.
  3. CPO ermöglicht über 100 Tbit/s effizienter, erschwert jedoch den Austausch einzelner Defekte im Vergleich zu Frontpanel-Steckmodulen.
