结构回波损耗是通信电缆的重要指标之一，而电缆绝缘线芯的水电容可综合反映生产线上的周期性缺陷。
SRL (structural return loss) is one of the important indicators of telecom cables, while the capacitance in water of cable may reflect the periodic defect of the production line.
故障定位或DTF模式指示驻波比或回波损耗水平在各点沿电缆长度和天线系统。
Fault location or DTF mode indicates VSWR or Return Loss levels at each point along the cable and antenna system length.
