CPO is 4.16x more energy efficient than pluggables, driving data center shift
casper_hansen_ · x · 2026-08-18
Cites analysis on the shift from pluggable optics to co-packaged optics (CPO) in data centers.
Efficiency comparison (pJ/bit):
- Pluggable: 20-25 pJ/bit (35dB loss)
- NPO: 10 pJ/bit (15-20dB loss)
- CPO: <5 pJ/bit (<6dB loss)
CPO is noted as 4.16x more efficient than pluggables, marking it as a key step in addressing the energy crisis.
