DCRU CAT 6A+ 模块

适用于WireXpert系列的测试模块

Article Number: 228271

适用于WireXpert系列的CAT6A+适配器能够使WireXpert 500、500-PLUS和4500设备在常规自动测试参数之外,测试双绞线屏蔽和非屏蔽以及局域网布线线缆上的直流电阻不平衡(DCRU)。CAT6A+适配器还有助于识别屏蔽线缆上的线缆屏蔽是否连接到正确的插座。

CAT 6A +模块的应用说明| DCRU

随着高达60或100W的高功率PoE(以太网供电)应用的推出,双绞线线缆的直流(DC)电阻成为一个重要的测试参数。如果线缆线对之间的直流电阻太高或线对之间甚至线对内的直流电阻相差太大,则该线对线缆的温度可能会高于线缆规格允许或连接器规格允许的温度。其结果是线缆将加速老化甚至损坏。此外,由于信号失真,还存在丢失数据的重大风险。因此,ISO/IEC、TIA和CENELEC将DCRU测试定义为一个可选参数,可以添加到常规的线缆认证中,为计划在特定线缆安装中使用大功率PoE做准备。

测试DC电阻不平衡功能

  • 根据TIA和IEC标准,测量双绞线之间和双绞线线对的直流电阻不平衡
  • 允许测试所有常规的自动测试参数,例如插入损耗(IL),近端串音(NEXT),回波损耗(RL),衰减近端串音比(ACR-N)和衰减远端串音比(ACR-F)以及相关的功率和值
  • 屏蔽完整性测试,以确定线缆屏蔽性的正确连接
  • 支持交叉线缆测试
