Abstract-This paper investigates common-mode propagation in shielded twisted pair cables. The common mode exhibits great potential for improving the throughput in emerging wireline systems. The design of corresponding transmission schemes over multipair copper cables requires accurate knowledge of the channel properties. We present measurement and modeling results and investigate the feasibility of using standard differentialmode models for data fitting in multiconductor transmission-line modelling of common-mode paths.
This paper investigates the achievable throughput of shielded twisted-pair (STP) copper cables exploiting alternative propagation modes. Treating the shield as joint common, we form wire-shield paths. The shield is expected to substantially reduce the amount of radio ingress entering the cable. Thus, we consider the impact of the shield effectiveness on the throughput limits. Using model and measurements presented in [1], we assess the limits in the presence of radio ingress assuming advanced transmission schemes such as multiple-input multiple-output (MIMO) techniques in terms of achievable throughput. The major finding of this paper demonstrates that throughput of wire-shield modes with sufficiently high shield effectiveness outperforms the state-of-the-art differential mode configuration.
