Internal optical interconnect distance of data centers
Intra-data center interconnects usually have lengths up to 2kms, campus interconnects up to 10km, and metro DCIs up to 100km, although there can be longer DCIs. As data centers become more complex and AI increases its demands on them, the intra-data center sector is increasing in complexity and. Optical interconnects use light to transmit data between devices, leveraging the principles of photonics to enable high-speed communication. Key Factors driving higher capacity Data Center Interconnect bandwidth include: Gigabit Ethernet growth ‐ The growth of 10 Gigabit Ethernet (GE), 25 GE and 40 GE network adapters Cloud IT: A single request can trigger. SHENZHEN, May 11, 2026 — As large language model training enters the era of trillion‑parameter scale, the internal interconnect distance of AI compute clusters is becoming the new "red line" that determines training efficiency.

Modular energy storage cabinet 1MWh for use in IDC Internet Data Center server rooms
Featuring lithium-ion batteries, integrated thermal management, and smart BMS technology, these cabinets are perfect for grid-tied, off-grid, and microgrid applications. A 1MWh BESS is where storage stops being "one cabinet" and starts becoming a site‑level power asset. For public cloud and large colo DCs, IDCs, and medium- and large-sized DCs of carriers, enterprises, governments, and financial institutions For small- and medium-sized DCs of governments, enterprises, and carriers, and small- and medium-sized IDCs For small equipment rooms in government. Sunwoda Energy, a global leader in battery solutions, proudly announces the global debut of two innovative products at MWC Barcelona 2024. The unveiling of the Outdoor Integrated Cabinet and the Intelligent IDC High-Voltage Modular Lithium Battery marks a significant milestone in Sunwoda Energy's. The application boundaries of commercial and industrial (C&I) energy storage are continuously expanding; system capacities are gradually upgrading from standard configurations—such as 100 kWh battery, 261 kWh battery, and 418 kWh battery—to 1 MWh-class containerized battery energy storage systems. It can be directly connected to the AC low- voltage side to provide reliable power support for various equipment and systems.

Foreign-invested Internet Data Centers
In four pilot areas including Beijing, Shanghai, Shenzhen and Hainan, foreign investors can now wholly own internet data centers (IDC). A UN Trade and Development report shows data centres captured more than one fifth of global greenfield investment in 2025. Data centres emerged as a major force shaping global investment in 2025, according to preliminary data published in a report on 20 January by UN Trade and Development (UNCTAD). Data centre investment is increasingly being directed outside traditional markets, as soaring demand for the power-hungry digital infrastructure leads developers to build capacity in alternative locations with access to plentiful affordable electricity. Ever since China's DeepSeek artificial intelligence (AI) chatbot made headlines in January, the country's cloud computing and internet industries have been racing to develop AI for consumers and businesses, according to Goldman Sachs Research. Within product segments, turnkey hyperscale is preferred by 42%, followed by powered shell by 28%.
