Industry brief covering infrastructure updates from Keysight, STT GDC, and Fluidstack providers.

Keysight Technologies, NTT Innovative Devices Corporation and Lumentum announced a joint demonstration of 448 Gbps data transmission using 224 GBaud PAM4 optical technology at the Optical Fiber Communication Conference and Exhibition (OFC) 2025. The partners noted that this collaboration addresses the escalating bandwidth demands of artificial intelligence and machine learning applications, enabling the development of power-efficient 3.2 terabit (Tbps) interfaces for future data center networks. The 448 Gbps transmission speed accelerates data movement between compute and network nodes, reducing latency and enhancing AI/ML model efficiency.

ST Telemedia Global Data Centres has unveiled an artificial intelligence-ready data center in New Town, Kolkata, India. The facility is designed to support the rising demand for AI computing with high-density rack configurations, advanced cooling systems and a scalable, modular structure. The new campus is certified with a TIA-942 Rated-3 Design and boasts a capacity of up to 25MW of IT load. The facility is built with concurrently maintainable infrastructure, ensuring zero Single Points of Failure (SPOF), and its modular design accommodates liquid cooling technologies, enabling high-performance computing workloads.

Developer Homer City Redevelopment (HCR) and construction firm Kiewit have signed a partnership to convert a former coal power station in Pennsylvania into a natural gas-powered artificial intelligence data center. The companies aim to convert a decommissioned 2GW coal-burning power station near Homer City, Indiana County, Pennsylvania into a 4.5GW natural gas powered data center campus spanning more than 3,200 acres. The construction of the facility is expected to begin this year, with commercial operations slated for 2027. The initial capital investment in the project is expected to exceed $10 billion for the power infrastructure and site readiness.

Fluidstack and Macquarie Group announced a strategic GPU financing deal to supply GPUs to artificial intelligence research labs across Europe. The financing structure, secured by the GPUs themselves, allows Fluidstack to provide artificial intelligence compute to customers like Mistral, Character.AI and Poolside without the burden of long-term commitments. Founded in 2017 at Oxford University, Fluidstack powers several artificial intelligence labs, including Mistral, Character.AI, Poolside and Black Forest Labs, and currently has over 100,000 GPUs under management. Fluidstack and Macquarie's specialized and asset finance team plan to expand their collaboration, with a focus on developing new financing models tailored to the special needs of artificial intelligence companies.
