ANSI-TIA-EIA-568-B.2-1_Cat.6_June_20_2002 ANSI/TIA/EIA-568B.2-1是六类的标准， 2002年6月正式通过的六类布线标准成为了TIA/EIA-568B标准的附录，它被正式命名为TIA/EIA-568B.2-1。该标准已被附录，使其更加完善。 TIA/EIA-568B六类布线系统标准要点：六类系统要求测试到250MHz频率。六类系统要求在200MHz时综合衰减串扰比（PS-ACR）≥0（即噪声干扰不超过有用的信号）。《ANSI/TIA/EIA-568-B.2-1Cat.6June202002》标准详解 ANSI/TIA/EIA-568-B.2-1 是针对六类（Category 6，简称CAT6）布线系统的一个关键标准，于2002年6月20日正式通过。此标准成为了TIA/EIA-568B系列标准的补充部分，以TIA/EIA-568B.2-1的形式存在，用于规范商业建筑中的电信布线系统，特别是平衡双绞线组件。六类布线系统是为满足更高带宽需求而设计的，适用于高速数据传输和千兆以太网应用。相比于五类和超五类系统，六类标准要求在更广泛的频率范围内测试，即达到250MHz的频率范围。这显著提高了系统的传输性能和带宽能力。标准的核心要求之一是综合衰减串扰比（PS-ACR，Power Sum Attenuation Crosstalk Ratio），在200MHz时，PS-ACR需达到或超过0分贝，这意味着在传输过程中，噪声干扰不应超过有用信号的水平。这一规定确保了六类电缆在高频率下仍能保持良好的信号质量，降低了数据传输错误的可能性。 TIA/EIA-568-B.2-1标准详细规定了4对100欧姆六类双绞线的传输性能规格，包括电缆、连接器、跳线和配线架等组件的设计、制造和性能测试。标准的制定旨在促进制造商和购买者之间的理解，确保产品的互换性，并推动产品持续改进。需要注意的是，TIA/EIA标准并不限制非成员制造或销售不符合标准的产品，同时，采用这些标准的用户应自行负责建立适当的安全和健康实践，以及确定适用的法规限制。此外，尽管TIA/EIA遵循美国国家标准学会(ANSI)的专利政策制定标准，但不承担任何专利权人的责任，也不对采用标准的各方承担义务。 ANSI/TIA/EIA-568-B.2-1 Cat.6标准的实施，对于推动通信行业的发展，保证网络基础设施的质量和可靠性具有重要意义。它为设计、安装和维护六类布线系统提供了明确的指导，确保了在高速网络环境下的高效、稳定运行。
