在固定接入和移动回传场景中，混合铜缆和光纤架构的使用都很有吸引力。这一趋势促使业界和学术界开始开发第四代宽带系统，其目标是在短铜环路上实现1gb /s的比特率。在这种情况下，在相对高频率下工作的短双绞线电缆的精确模型是关键因素。这项工作描述了新的参数化电缆模型，该模型包含四个重要特征：支持高达200 MHz的频率，参数少，因果脉冲响应，并且需要相对容易的拟合程序。结果表明，该模型对单段具有良好的精度，这是G.fast部署所期望的拓扑结构。
The use of a hybrid copper and fiber architecture is attractive in both fixed access and mobile backhauling scenarios. This trend led the industry and academia to start developing the fourth generation broadband system, which aims at achieving bit-rates of 1 Gb/s over short copper loops. In this context, accurate models of short twisted-pair cables operating at relatively high frequencies are key elements. This work describes new parametric cable models that incorporate four important characteristics: support of frequencies up to 200 MHz, few parameters, causal impulse responses and require relatively easy fitting procedures. The results show that the models achieve good accuracy for single segments, which are the expected topology for G.fast deployments.
