：在MDA（主配线区）、IDA（中间配线区）、HDA（水平配线区）等关键布线节点，机柜最小宽度提升至800mm（约31.5英寸），以容纳高密度光缆及连接器。对比传统24英寸机柜已不再适配现代高密度布线，800mm机柜更能满足AI、高性能计算所需的光纤密度要求；
Driven by massive data growth and the low-latency networking requirements of AI architectures, TIA-942-C revamps physical layer infrastructure parameters:
: Automatically isolates failures. The infrastructure tolerates a single worst-case fault without causing a data center outage. Key Updates in TIA-942-C vs. TIA-942-B tia942c pdf full

ANSI/TIA-942-C is the third revision of the globally adopted Telecommunications Infrastructure Standard for Data Centers, published by the Telecommunications Industry Association (TIA) in May 2024. It is an American National Standard that specifies the minimum requirements for all physical infrastructure within a data center, covering site location, architecture, electrical systems, mechanical systems, fire safety, telecommunications, security, and more.
The standard, published in May 2024, is the latest revision of the globally recognized Telecommunications Infrastructure Standard for Data Centers . It provides a comprehensive framework for designing and building resilient, scalable, and efficient data centers, ranging from small edge facilities to massive hyperscale environments. Key Scope and Infrastructure Pillars The standard, published in May 2024, is the
