近几年手机局域网(LAN)的发展非常迅速,特别是高速局域网,即100M的局域网。尽管真正实用的有统一标准的100M网尚未有最终结果,但很多网络用户已经考虑到其应用的可能,其中最主要的表现就是在安装新的网络时,用户都大量采用互类(UTP Cat5) 即100M的双绞线,从而为将来做好准备。但是由于绝大多数用户并不马上安装100M的网,所以这些电缆的安装能否真正运行100M的网上就成了一个问题。也就是说,用户如何保护自已的先期投资呢?如何认证用户所安装的五类线是符合规定的,如EUA/TIA,但不幸的是,EIA/TIA尚未对CTP Cat5订出最后的标准,目前的情况是,EIA/TIA已订出规定的草本,即TSB67
In recent years, the development of mobile LAN has been very rapid, especially high-speed LAN, that is, 100M LAN. Although the 100K net in a practical and uniform standard has not yet reached the final result, many network users have already considered the possibility of their applications. The most important performance of the 100M net is that users generally make extensive use of inter-category (UTP Cat5) That is 100M twisted pair, so as to prepare for the future. However, since the vast majority of users do not immediately install 100M network, so the installation of these cables can really run 100M online has become a problem. In other words, how can users protect their upfront investment? How to certify that the five types of cables installed by users are compliant, such as EUA / TIA, but unfortunately, EIA / TIA has yet to set the final standard for CTP Cat5, The current situation is that the EIA / TIA has set out the prescribed herb, TSB67
