Weekly Intelligence Brief on developments in AI and networking technologies - Week of November 3, 2025

Key Takeaways

• Microchip Technology introduced Optical Ethernet PHY transceivers supporting up to 25 Gbps.
• Automated Model Deployment (AMD) partnered with the U.S. DOE for two Artificial Intelligence (AI) supercomputers: Lux and Discovery.
• Applied Digital achieved Ready for Service for the first phase of Polaris Forge 1 AI Factory Campus.
• New AI infrastructure developments support growing demand in industrial applications.

Microchip Technology introduced a new series of Optical Ethernet PHY transceivers that deliver speeds of up to 25 Gbps, catering to the demand for networking solutions suitable for long distances and harsher environments. These transceivers support link lengths of up to 10 kilometers over Single-Mode Fiber (SMF) and enhance security and scalability over traditional copper-based Ethernet.

The new transceivers incorporate IEEE 1588 Precision Time Protocol (PTP) for synchronization accuracy, essential for time-sensitive applications in industrial automation and telecommunications. Charlie Forni, corporate vice president at Microchip, said, “Design engineers are looking for solutions that simplify complex networking systems.” The products also support Media Access Control Security (MACsec) encryption for data integrity.

AMD announced plans with the U.S. Department of Energy for two supercomputers, Lux and Discovery, aimed at enhancing United States capabilities in AI and High performance computing (HPC). Lux is set to be operational in early 2026, followed by Discovery in 2028. The initiative involves an investment of $1 billion from public and private entities, with aims to boost scientific research and national security.

Applied Digital achieved a Ready for Service milestone for the first 50 Megawatt (MW) phase at Intelligent Transportation System (ITS) Polaris Forge 1 AI Factory Campus in North Dakota. This facility aims to support the increasing demand for AI infrastructure and includes a projected revenue from a lease agreement of $11 billion with CoreWeave. The Polaris Forge 1 facility is designed to scale operations effectively for HPC markets and incorporate efficient technologies for optimal performance.
