Marvell CEO Predicts Photonics Will Replace Copper in Datacenters
TL;DR. Marvell’s CEO Matt Murphy stated photonics will replace copper interconnects in datacenters within a decade, citing increasing bandwidth demands. - Nvidia CEO Jensen Huang supports this claim, noting the limitations of copper cabling at high speeds. - Copper's signal reach halves with every bandwidth double, making optical connections necessary even within racks. - While optics offer greater reach, power consumption and reliability remain challenges for widespread adoption.
- Marvell CEO Matt Murphy forecasts silicon photonics will replace copper interconnects in datacenters within a decade.
- Nvidia CEO Jensen Huang highlighted the limitations of copper at high bandwidths, stating 400 Gbps reduces copper reach to meters.
- Marvell is preparing for optical connections to become standard even inside datacenter racks.
- Power consumption and reliability are key challenges for the broader implementation of optical technologies.
