| Abstract(in English) | VDSL service has been progressed because it achieves high-speed access network with copper premises cables. Although inexpensive FTTH service has been offered by VDSL systems, the link between a VDSL transceiver unit at the optical network unit and a VDSL transceiver unit at the remote site is influenced by electromagnetic disturbance induced into premises cables. The influence of different configurations and different types of premises cables on the longitudinal conversion loss (LCL) or the immunity of VDSL systems has also been investigated. However, although the influence has been investigated by using the measurement systems on the ground plane, the premises cables are not laid out on the ground plane or near by materials of metal in an actual installation. In this paper, we have investigated the influence of the distance between the premises cable and the ground plane on the LCL of the cable or the immunity level of the VDSL system. As a result, the LCL of the cable has been varied depends on the distance, and the immunity level has been correlated with the LCL. |
