随着信息社会发展的需求,人们对网络传输速度,质量的要求越来越高;因此,影响网络品质的关键因素——电缆布线问题也越来越被信息界人士所重视。目前被业界人士选用的电缆有三、四、五类电缆及光纤。同三、四、五类铜缆相比,光纤具有许多无可比拟的优点,它不受外部射频干扰,且传输距离远。理论上说,六类网络产品也是不可与之比拟的。下面表格可以使我们一目了然:
With the development of information society, people have higher and higher requirements on the speed and quality of network transmission. Therefore, the key issue affecting the quality of network, the issue of cable routing, is also paid more and more attention by the people in the information industry. At present, the cables selected by industry people have three, four and five types of cables and optical fibers. Compared with the three, four, five types of copper cables, optical fiber has many unparalleled advantages, it is not subject to external radio frequency interference, and the transmission distance. In theory, the six types of network products are also incomparable. The following table can make us at a glance:
