Powering the Digital Future With Measurement You Can Trust
Data centers are a backbone of modern society. Cloud platforms, AI, hyperscalers, and global connectivity all depend on infrastructure that operates continuously, cleanly, and efficiently. As workloads intensify and energy consumption rises, operators face challenges in grid integration, power efficiency, reliability, and thermal management.
The Data Center Power Chain: From Utility to Silicon
Modern data centers operate at enormous electrical and thermal scale, supplying power from the utility grid through transformers, UPS systems, generators, power distribution units, and server power electronics (PSU). The resulting heat is removed through air or liquid cooling systems.
Each stage introduces its own measurement challenges, from verifying power quality at the grid interface to characterizing UPS performance, transformer efficiency, PDU loading, and the dynamic power profiles of CPUs and GPUs in high-density compute environments.
Silicon Photonics and Optical Links in the Data Center
Alongside the power chain, data centers rely on silicon photonics, optical transceivers, and high-bandwidth interconnects to move data at scale. Measuring them demands accurate analysis of optical modulation, signal integrity, data error rates, and the performance of next-generation optical links.
