In brief: GlobalFoundries and Marvell are extending their long-running collaboration with additional silicon-germanium manufacturing capacity in Burlington, Vermont. The components target 200Gbps-per-lane optical links and future near- and co-packaged optics. The companies did not disclose the expansion size or availability date.
The bottleneck between accelerators
The multi-year agreement expands existing production. GlobalFoundries manufactures the SiGe technology, while Marvell uses it in optical transmitters and receivers for pluggable transceivers, Near-Packaged Optics (NPO) and Co-Packaged Optics (CPO). SiGe combines silicon manufacturing with the higher-frequency characteristics of germanium bipolar transistors, useful for drivers and receiver amplifiers that move high-rate electrical signals into and out of the optical chain.
GlobalFoundries rates its current generation at 200Gbps per lane and promises a roadmap to higher speeds. That figure describes one optical channel, not automatically a module's aggregate throughput. Systems combine multiple lanes, while modulation, encoding, error correction and the rest of the signal path also determine usable capacity.
Pluggable optics sit at the switch edge. NPO moves optics closer to the switch ASIC; CPO places them beside the compute chip in the same package. Shorter electrical paths can reduce power and signal loss, but make cooling, serviceability, yield and multi-vendor interfaces harder. OIF therefore treats energy-efficient electrical and optical interfaces as a dedicated standardisation track.
Pandorex Analysis
The capacity deal does not show that CPO has reached volume deployment. It covers both market-ready pluggables and more tightly integrated architectures. Marvell gains a manufacturing base across several transition stages, while GlobalFoundries loads specialty processes rather than leading-edge logic nodes.
This matters for AI infrastructure because accelerators increasingly wait for data unless interconnect bandwidth scales with compute. The agreement addresses that bottleneck at component level. Without wafer counts, investment, purchase volumes or a production start, however, the capacity increase cannot be quantified. Reuters confirms the expanded agreement; performance and roadmap claims come from the companies.
