Marvell wants to be a copper topper, bets $115B on photonics leader to push optical networking
IP house believes optics demand is going to explode as Nvidia and others eye bigger systems
In an all-stock deal valued at $115 billion, Marvell Technology is set to acquire photonics giant Lumentum, aiming to become the dominant player in the future of AI networking. The transaction will help Marvell fill key gaps in its photonics portfolio, including high-performance laser sources, optical transceivers, optical circuit switches, and specialized compound semiconductor manufacturing capabilities involving indium phosphide.
The push towards higher speed interconnects and larger compute domains signifies the move to photonics, as traditional copper interconnects are struggling to keep up with the demand. As interconnect speeds push beyond 400 Gbps per lane, the limitations of copper become apparent, necessitating denser and hotter rack systems. Photonics offer a solution to these scaling laws, enabling signal transmission over kilometers while reducing power and cooling requirements per rack.
The acquisition of Lumentum will position Marvell as a comprehensive solution provider for AI infrastructure providers, equipping them with the photonics components necessary for scaling their systems across entire aisles.
