			<content:encoded><![CDATA[<p>自2017年开年以来，<span class='wp_keywordlink_affiliate'><a href="http://www.faxytech.com/tag/cat8%e7%b1%bb" title="查看 CAT8类 的全部文章" target="_blank">CAT8类</a></span>的<span class='wp_keywordlink_affiliate'><a href="http://www.faxytech.com/tag/%e5%b8%83%e7%ba%bf%e6%a0%87%e5%87%86" title="查看 布线标准 的全部文章" target="_blank">布线标准</a></span>吵得沸沸扬扬，大家都对CAT8的话题很热心，也很想了解下行业新技术，深圳连讯达今天为大家介绍CAT8类布线的相关标准。</p>
<p><strong>8类布线相关的标准和主要要求如下：</strong></p>
<p>2016年9月8日发布于的 IEEE 802.3bq 25G/40GBASE-T：此标准规定了双绞线信道上应用的最小传输特性以支持 25 Gbps 和 40 Gbps 的基于双绞线的布线。</p>
<p>2016年6月30日发布的 ANSI/TIA-568-C.2-1：规定了8类通道和永久链路并包括有电阻不平衡、TCL、ELTCTL 的限制。</p>
<p>2016年11月10日发布于的 ANSI/TIA-1152-A：规定了8类的现场测试仪测量和精度要求，包括8类测试仪的新 &#8220;2G&#8221; 精度要求。</p>
<p>2017将预期发布 ISO/IEC 标准，包括规定了 I/II 类信道和永久链路的 ISO/IEC 11801-99-1 以及规定了测试仪测量和精度要求的 IEC 61935-1 Ed5.0，包括与 ANSI/TIA1152-A 相同的 &#8220;2G&#8221; 要求。</p>
<p>&nbsp;</p>
<p><a href="http://www.faxytech.com/wp-content/uploads/2017/03/cat8.jpg" class="highslide-image" onclick="return hs.expand(this);"><img class="alignnone size-full wp-image-8670" title="cat8布线标准" src="http://www.faxytech.com/wp-content/uploads/2017/03/cat8.jpg" alt="cat8布线标准" width="500" height="331" /></a></p>
<p>&nbsp;</p>
<p><strong>8 类解决方案预计何时发布？</strong></p>
<p>撰写此文时，尚无任何供应商发布 8 类布线解决方案，虽然 <span class='wp_keywordlink'><a href="http://www.faxytech.com/products/cabling-system/panduit" title="Panduit">Panduit</a></span> 和 Leviton 宣布并展示了经过独立验证的解决方案。</p>
<p><strong>8 类布线的情况如何？</strong></p>
<p>8 类解决方案专用于支持最长距离 30 米、速率高达 40 Gbps (40GBASE-T) 的以太网，使其成为主要面向数据中心的解决方案。<span class='wp_keywordlink'><a href="http://www.faxytech.com/products/testers/cable" title="铜缆测试仪">铜缆</a></span>布线安装时成本较低，但是可以大大节省相关的耗电和电子成本。如果 8 类/ 40GBASE-T 得到广泛部署，那么支持它的交换机和服务器连接会比使用光纤的成本低得多。此外，25/40GBASE-T 标准支持自动协商机制，这为数据中心运营商提供了方便。</p>
<p>另外将来其他应用也可能会采用 8 类。</p>
