摘要
本文研究介质温度系数对五类非屏蔽双绞线电气性能的影响,讨论传输延迟、UTP电阻以及衰减的温度修正公式。对Fluke测量仪所测试到的数据结果进行详细分析,并对网络综合布线中存在的传输介质工作温度和长度的问题给出提高网络性能的方法,提出选用低值温度系数对UTP进行优化的建议。
The paper studied that the temperature coefficient has effect on electric capability of Unshielded Twisted Pair, and brought forward some formulas of revise of temperature about Propagation Delay, Resistor and Attenuation. It detailed analysis for the Fluke testing result of data. Suggestions of optimization on the solutions to the problem of medium temperature and length probably occur in network structured cabling are given by the temperature coefficient of lowness.
