摘　　要：结构化布线工程的最后一步是对布线系统的测试和评估,电缆的性能测试经常被忽视,基本指标有:近端串扰,综合近端串扰,衰减串扰比,等效远端串扰,综合等效远端串扰,回波损耗,延迟抖动等。The last step of network cabling is to test and evaluate the cabling system. The performance tests of cable is usually omitted. The paper describes basic items used to test category 5 UTP performance, such as near-end crosstalk,power sum near end cross talk, attenuation-to-crosstalk ratio, equal level far-end crosstalk, power sum equal level far-end crosstalk, return loss,and delay skew.

关 键 词：TIA/EIA TSB-67 近端串扰 衰减串扰比 综合近端串扰 等效远端串扰 综合等效远端串扰
