使用最初为电话而安装的铜线网络进行高速通信是主要的互联网接入技术之一。在过去的二十年中，已经开发、标准化和安装了被称为数字用户线路（DSL）的技术的若干变型。从本质上讲，DSL通过利用铜缆信道的宽带来实现高速率。电缆越短，可以有效用于通信的频带就越宽。目前的DSL标准预见使用高达30MHz的频带。电缆性能已通过测量，表征和建模高达30 MHz的频率进行了研究。最近的研究表明，从技术和经济的角度来看，进一步利用非常短的电缆（高达200米）并使用30 MHz以上的频带是可行的。进一步评估和设计这种超宽带铜线（UWBC）系统的先决条件是将现有电缆模型扩展到更高的频率。本文介绍了频率高达200MHz的10对不同长度电缆的插入损耗和串扰耦合的宽带测量结果。我们比较的结果与电缆模型，建立在30兆赫范围内的外推。
High-speed communication using the copper network, originally installed for telephony, is one of the dominant Internet access techniques. Several variants of a technology referred to as digital subscriber line (DSL) have been developed, standardized and installed during the last two decades. Essentially, DSL achieves high rates by exploiting wide bands of the copper cable channel. The shorter the cable, the wider the band that can be used efficiently for communication. Current DSL standards foresee the use of bands up to 30MHz. Cable properties have been studied by means of measurements, characterization and modeling up to frequencies of 30MHz. Recent investigations have shown that it is feasible both from technical and from economical point of view to exploit very short cables (up to 200m) even further and use bands above 30MHz. A prerequisite for further evaluation and the design of such ultra-wideband copper (UWBC) systems is the extension of existing cable models to higher frequencies. This paper presents wideband measurement results of insertion loss and crosstalk coupling in a 10-pair cable of various length values for frequencies up to 200MHz. We compare the results with extrapolations of cable models that are established in the 30MHz-range.
