近几个月以来,人们一直在讨论用5类电缆传输155Mbps不归零信号的可能性。尽管ATM 155Mbps符合5类电缆传输标准,人们仍对用5类电缆传输高于 100MHz信号抱怀疑态度。5类电缆传输155Mbps取决于以下几个重要因素:不归零信号中频率高于100MHz部分的能量总和、交调失真衰耗比和信号接收带宽。通过测定以上参数表明:用标准的5类电缆
In recent months, people have been talking about the possibility of transmitting 155Mbps non-return to zero signals with Category 5 cable. Although ATM 155Mbps meets Category 5 cable transmission standards, people are still skeptical of transmitting over 100MHz signals on Category 5 cables. Category 5 cable transmission 155Mbps depends on several important factors: not return to zero signal frequency above 100MHz part of the energy, crosstalk attenuation and signal reception bandwidth. By measuring the above parameters indicate: with a standard Category 5 cable
