The ADSL technology has been successfully promoted in Taiwan today. In order to extend the fiber service to customers and increase service bandwidth, the FTTB strategy combined with EoVDSL solution has been proposed to provide integrated services including internet, video and voice services. In this paper, we will introduce the application structure of FTTB and EoVDSL technology. We also simulate and analyze the environment of the copper wires in the building in Taiwan, and observe the different loop structure and the situation of attenuation in high frequency response, which are due to different wire gauge and home network. Then, we show how to avoid crosstalk noise appropriately in DMT-based and QAM-based VDSL system and describe VDSL standard and product development.
