消费者数据使用量的增加增加了对无线和有线系统电信中更高数据速率的需求。为了满足有线服务增加数据速率的需求，一种可能性是切换到更高的频率，超出通常用于数字用户线路（DSL）服务的 MHz 范围频率。在这项工作中，我们研究了通过波导结构传输的 200 GHz 信号的通道特性，该结构旨在近似模拟通常用于 DSL 传输的配对电话电缆的类型。我们报告了此类通道的衰减特性，并探索了利用此多模通道的模式多样性的现实矢量化场景可实现的数据速率。我们发现，在短距离内，每秒太比特数量级的聚合数据速率是可行的。
The rise in consumer data usage has increased the demand for higher data rates in telecommunication in both wireless and wired systems. In order to meet the demands for increased data rates for wired services, one possibility is to switch to higher frequencies, beyond the MHz-range frequencies typically used in digital subscriber line (DSL) services. In this work, we investigate the channel properties of a 200 GHz signal transmitted through a waveguide structure that is designed to approximately emulate the type of paired phone cable typically used for DSL transmissions. We report the attenuation characteristics of such a channel and explore the achievable data rates of a realistic vectored scenario that exploits the modal diversity of this multi-mode channel. We find that aggregate data rates on the order of terabits per second are feasible over short distances.
