Abstract

Phantom mode has been proposed to improve G.fast applications. However, the most of the phantom mode systems deploy the first phantom layer only. Nevertheless, this work analyses the feasibility of a system, which deploys an additional phantom mode level, called second phantom layer. The entire system, first and second layers and differential modes, can reach bit rates up to 15 Gbps in lengths up to 30 m, when vectoring is applied. The achieved levels of EVMs are according the 3GPP standard even under Ethernet interfering influence.
