铜缆真的会被光纤所取代吗?现在作出这一定论似乎为时过早。人们曾经认为非屏蔽双绞线在5类100MHz 时已经达到极限,许多用户和厂商把注意力转向了光纤,认为光纤是 IT 设施必然的过渡途径。光纤从各个方面解决了非屏蔽双绞线的缺点:它具有更高带宽,允许的距离更长,安全性更高,完全消除了 RFI Is copper really replaced by fiber? It seems too early to make that conclusion. Once considered unshielded twisted pair has reached the limit of five types of 100MHz, many users and vendors have turned their attention to the optical fiber, that optical fiber is the inevitable transition path IT facilities. Optical fiber solves the disadvantage of unshielded twisted pair in all its aspects: it has higher bandwidth, longer distances and greater safety, completely eliminating RFI
