ANSI/TIA-568.1-E is the current "Commercial Building Telecommunications Infrastructure Standard," published in March 2020
Perhaps the most significant change in the evolution leading to and including the E revision was the formal recognition of Category 6A (Cat 6A) cabling.

The ANSI/TIA-568.1-E standard (2020) acts as the foundational "umbrella" document for commercial building telecommunications infrastructure, outlining the required hierarchical star topology for structured cabling. It defines essential system architecture, including horizontal cabling limits of 90 meters, to ensure vendor-neutral performance. Access the official standard for purchase through ANSI Webstore.
Even with these updates, the standard still relies on the six "pillars" of structured cabling that have kept us connected for decades: ANSI/TIA-568
