随着高速宽带通信的发展,传统的双绞铜线电缆的技术性能已不能满足未来的布线系统提出的更高要求。为了解决这个问题,美国TLA/EIA(电信工业协会与电子工业联盟)和ISO/IEC(国际标准化组织与国际电工技术委员会)最近为改善和提高双绞铜线电缆的性能做了大量的工作,例如,修改了现有的第5类双绞铜线的技术规范和起草了新的技术规
With the development of high-speed broadband communications, the technical performance of the traditional twisted pair copper cable can no longer meet the higher requirements of future wiring systems. To solve this problem, the United States recently TLA / EIA (Telecommunications Industry Association and the electronics industry alliance) and ISO / IEC (International Organization for Standardization and International Electrotechnical Commission) to improve and enhance the performance of twisted-pair copper cable has done a lot of work, For example, the technical specifications of existing Category 5 twisted pair copper wires have been modified and new technical specifications have been drafted
