Which standard governs structured cabling in data centers?

The appropriate standard governing structured cabling in data centers is ANSI/TIA-942. This standard specifically outlines the requirements and guidelines for the physical infrastructure of data centers, addressing aspects such as the design and layout of spaces, telecommunications rooms, and the pathways and spaces that support structured cabling.

While ISO/IEC 11801 and TIA/EIA-568 also reference cabling standards, they focus more broadly on general telecommunications cabling and are applicable in a variety of environments, not limited to data centers. IEEE 802.3 pertains to Ethernet networking standards and does not cover aspects of cabling infrastructure specifically related to data centers.

ANSI/TIA-942 provides crucial insights related to the necessary cabling systems that optimize performance and ensure reliability in data center operations, making it the most relevant standard for structured cabling in this specific context.
