As high-performance compute clusters scale to tens of thousands of GPUs, traditional copper interconnects are reaching physical limits regarding signal degradation and power consumption. Silicon photonics solutions are rapidly filling the void.
Energy Efficiency Metrics
Optical interconnects consume up to 30% less power per gigabit transferred compared to copper alternatives over distances exceeding two meters, substantially reducing cooling requirements.
Manufacturing and Integration
Semiconductor foundries are integrating co-packaged optics directly onto silicon substrates, though yield optimization remains a primary challenge for volume scaling.
