值得一提的是，TIA于2026年进一步启动了增补项目的立项，专门聚焦于人工智能（AI）计算对数据中心基础设施的独特需求，反映了该标准与时俱进的发展特点。

A primary reason organizations seek the full TIA-942-C text is to understand the Rating System. The standard evaluates data centers across four distinct Ratings (historically referred to as Tiers), indicating the level of resilience and uptime. Rating Level Descriptive Name Redundancy Level Concurrently Maintainable? Fault Tolerant? Rated (Basic) Rating 2 Redundant Component Rating 3 Concurrently Maintainable Rating 4 Fault Tolerant 2(N+1) or 2N

的发布不仅是标准版本的例行更新，更是对数据中心基础设施设计理念的一次重新定义。它全面回应了以下三大趋势的深刻影响：

The "C" revision modernized the standard to include technologies that have become standard since the "B" revision: Fault Tolerant

这是TIA-942-C中最具象征意义的结构性变更之一。之前的数据中心常常使用的是24英寸（约600mm）宽的机柜，但在AI和高性能计算时代，这些机柜难以容纳现代光纤的高密度布线要求——光纤堆积常导致机柜门无法关闭或布线被压坏。

The standard continues to use a four-level rating system to define data center resiliency : : Basic Site Infrastructure (no redundancy). Rated 2 : Redundant Component Site Infrastructure. Rated 3 : Concurrently Maintainable Site Infrastructure. Rated 4 : Fault Tolerant Site Infrastructure . TIA-942-C Release, What Has Changed? Rated 2 : Redundant Component Site Infrastructure

The physical layer is where TIA-942-C introduces its most restrictive and actionable design updates. These changes directly combat the cable congestion and signal degradation caused by high-density AI clusters [1.23].

Efficiency tracking is now anchored to global standards. Energy efficiency benchmarks like Power Usage Effectiveness (PUE) must now actively reference , pushing operators toward comprehensive tracking of Energy Reuse Factors (ERF) [1.9]. Decentralization and the Edge Infrastructure
