大量的业务越来越依赖于网络,也对网络的传输质量和可靠性提出了更高的要求,这就要求网络有很好的传输性能。大多数的网络仍然使用非屏蔽双绞线(UTP)作为主要的传输介质,干扰和衰减是影响网络传输性能的重要因素。影响干扰和衰减的因素复杂,应该对这些因素加以分析并且在工程实践中削弱其影响。 A large number of businesses are increasingly dependent on the network, but also put forward higher requirements on the quality and reliability of network transmission, which requires that the network has good transmission performance. Most networks still use unshielded twisted pair (UTP) as the main transmission medium, and interference and attenuation are important factors that affect network transmission performance. The factors that affect interference and attenuation are complex and should be analyzed and their impact diminished in engineering practice.
