The End of the Copper Era: Broadcom and Marvell Usher in the Age of Co-Packaged Optics for AI Supercomputing

As artificial intelligence models grow from billions to trillions of parameters, the physical infrastructure supporting them has hit a “power wall.” Traditional copper interconnects and pluggable optical modules, which have served as the backbone of data centers for decades, are no longer able to keep pace with the massive bandwidth demands and extreme energy requirements of next-generation AI clusters. In a landmark shift for the industry, semiconductor giants Broadcom Inc. (NASDAQ: AVGO) and Marvell Technology, Inc. (NASDAQ: MRVL) have successfully commercialized Co-Packaged Optics (CPO), a revolutionary technology that integrates light-based communication directly into the heart of the chip.

This transition marks a pivotal moment in the evolution of data centers. By replacing electrical signals traveling over bulky copper wires with laser-driven light pulses integrated onto the silicon substrate, Broadcom and Marvell are enabling AI clusters to scale far beyond previous physical…
