Abstract

We investigate the influence of a high-speed power line communication (PLC) signal induced into the very high-bit-rate digital subscriber line (VDSL) modem from the power line on the communication performance of VDSL. Differential-mode signal transmission loss between input signal at the modem´s mains terminal and output signal at the modem´s telecommunication terminal was estimated by using a 4-terminal-pair-network-model of the VDSL modem. We estimated modems supplied by two manufactures. The transmission losses were more than 45 and 70 dB and the throughputs were degraded when the signal power of the VDSL were attenuated by more than 38 and 45 dB, respectively
