Computing Interconnects
Co-Packaged Optics
An emerging networking technology that integrates optical components directly onto chip packages to replace pluggable transceivers and, increasingly, copper itself — optical links deliver 4-20x more throughput per watt than copper, which industry veterans describe as having hit a 'power wall' at the scale modern AI clusters now require.

Co-Packaged Optics's Timeline
A sourced, dated history of Co-Packaged Optics's key moments — founding to present.
2024–2026 · NVIDIA and Broadcom race to dominate
NVIDIA and Broadcom began racing to dominate co-packaged optics, with NVIDIA fielding Quantum-X and Spectrum-X Photonics switches and Broadcom focusing on Ethernet switching via Tomahawk 6 and Jericho 4, as optical links began replacing copper at the AI cluster 'power wall.'
How These Connections Evolved
How a relationship changed over time, not just its current state — sourced, dated, and traceable.
Co-Packaged Optics ↔ NVIDIA
2024–2025
NVIDIA introduced Quantum-X and Spectrum-X Photonics co-packaged optics switches, targeting the networking 'power wall' that copper interconnects hit at modern AI cluster scale.
Now
NVIDIA develops co-packaged optics switches, including Quantum-X Photonics and Spectrum-X Photonics, built on TSMC's silicon photonics packaging process.
Co-Packaged Optics ↔ Broadcom
2024–2025
Broadcom developed co-packaged optics for its Tomahawk 6 and Jericho 4 Ethernet switching platforms, competing directly with NVIDIA's Quantum-X/Spectrum-X Photonics approach for AI cluster networking.
Now
Broadcom independently develops co-packaged optics technology for its Ethernet switching platforms, competing with NVIDIA's approach.
Co-Packaged Optics ↔ Taiwan Semiconductor Manufacturing Company
2024–2025
TSMC's COUPE silicon-photonics packaging process became the manufacturing foundation for both NVIDIA's and Broadcom's competing co-packaged optics switch lines.
Now
Co-packaged optics manufacturing depends on TSMC's COUPE silicon photonics packaging process, which both NVIDIA and Broadcom rely on for their optical switch products.
