An optical module is a device specifically designed for data transmission, converting electrical signals into optical signals and vice versa. It is installed in switches, servers, and network interface cards, enabling high-speed data transmission such as 100G, 400G, or 800G. An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. For GPUs, AI accelerators, and high-performance CPUs in large-scale clusters, optical modules have become inevitable. The core reason is that as computing performance scales rapidly, the real system bottleneck shifts from compute power to interconnect bandwidth.
[pdf] China officially activated world's first offshore wind-powered underwater data center entering full commercial operation off coast of Shanghai's Lingang Special Area. The project began in 2023 with the deployment of the first unit near the coast of Hainan Island in the southernmost part of the country. Today, a new unit dedicated to AI computations. Inside a 200-square-meter room at the Tianshan Smart Valley Advanced Computing Cluster in the city of Hami, Xinjiang Uygur Autonomous Region, hundreds of servers hum day and night. In just over a year, the likes of telecom giants, cloud computing service providers and tech firms have moved into. In a groundbreaking leap for global technology infrastructure, China has launched the world's first commercial AI-powered underwater data center.
