Summary of NVIDIA's Optical Interconnection Developments Company Overview - **Company**: NVIDIA (Ticker: NVDA US) - **Industry**: AI Networking and Optical Interconnection Key Points Industry Developments - NVIDIA is expected to incorporate CPO (Co-Packaged Optics) into its 2027 Rubin Ultra architecture, following Google's adoption of OCS (Optical Circuit Switching) for its TPU V7, which interconnects over 9,000 chips, surpassing NVIDIA's projected deployment of 576 dies in 2027 [1][2] - The transition to CPO for rack-to-rack interconnects is anticipated to enhance power consumption, latency, density, and cost efficiency compared to AOC (Active Optical Cable) [2] Product and Technology Insights - NVIDIA's scale-up optical solutions may arrive sooner than expected, with CPO being considered for the 576-die architecture starting in the second half of 2027 [2] - Compute trays and switch trays will continue to use PCB backplane connectivity, while rack-to-rack interconnects are likely to adopt CPO-based optical interconnects [2] - The scale-up CPO presents an incremental opportunity for the optical interconnect supply chain, with key beneficiaries including companies like LITE, Sumitomo, and Browave [3] Market Expectations - NVIDIA's scale-out CPO switch is projected to have deployment figures of 2,000, 20,000, and 35,000 units in 2025, 2026, and 2027 respectively [4] - The anticipated demand for NVIDIA's OIO (Optical Interconnection) solution is expected to coincide with the Feynman architecture, driving demand for CW lasers, FAUs, and optical engines [4] Risks - Potential risks include deceleration in AI demand, geopolitical uncertainties, and increased competition within the industry [5] Rating and Performance Expectations - NVIDIA is rated as a "Buy," indicating an expectation to outperform the benchmark by more than 15% [6] Additional Considerations - The report emphasizes that the CPO penetration rate may not be significant in the 1.6T generation due to factors such as maturity and technical reliability [4] - The supply chain for scale-up CPO is similar to that of scale-out CPO, indicating a consistent market structure [3] This summary encapsulates the critical insights and projections regarding NVIDIA's advancements in optical interconnection technology and its implications for the industry.
