Standard bending radius of optical cable entering the equipment room
The normal recommendation for fiber optic cable is the minimum bend radius under tension during pulling is 20 times the diameter of the cable (d). Proper bend radius control ensures the integrity of optical performance and protects the glass. For example when a cable is bent around a corner, bend radius may be appropriate, but if the cable is used with pulleys or capstans during pulling, then left stored in loops, the diameter of the pulley, capstan or storage loop may be more descriptive. Thus we will define and use both terms. Ignoring these rules leads to improper installation, signal loss, and costly cable damage. -
China New Energy Big Data Center
Ningxia, China - May 3, 2026 - China has brought online its first large-scale renewable energy project designed to supply power directly to data centers, marking a significant step in aligning artificial intelligence-driven computing demand with national decarbonization.

Ningxia, China - May 3, 2026 - China has brought online its first large-scale renewable energy project designed to supply power directly to data centers, marking a significant step in aligning artificial intelligence-driven computing demand with national decarbonization goals. The project, located. China's first large-scale project to supply renewable energy directly to data centres started operating on Saturday. The opening of the plant in the northwestern region of Ningxia, a major centre for wind and solar power, comes as Beijing tries to balance increased demand for electricity and. China is on course to nearly double its data center capacity within five years, with 28 gigawatts (GW) of new projects expected to come online by 2030, adding to the 32 GW already installed as of the end of last year, according to new analysis from Rystad Energy., 21Vianet, also consider Huawei-linked infrastructure suppliers). That tremendous increase in demand is due to power. -

Is it mandatory to use cable trays for cables
NEC Article 392 governs cable tray systems. Grounding and bonding are mandatory for metallic trays. Tray fill limits must be calculated properly. Firestop. However, not all installations require cable trays, and it's essential to understand when and why you should use them. These systems, made from metal or plastic, are open structures designed to support electrical conductors, ensuring proper organization and safety. Here's what you need to know: Cable Types: Only use. Answer: No. 305(a)(3), or comparable standards promulgated by States operating OSHA-approved State plans. In addition, this document contains several references to provisions of the National Electric Code. -
