摘要：
A broadband access system using subcarrier multiplexing on optical fibre and asymmetric digital subscriber lines (ADSL) or very high-speed digital subscriber lines (VDSL) on unshielded twisted-pair is proposed to provide broadband access. In this hybrid-fibre/twisted-pair (HFTP) system, the digital multiplexing/ demultiplexing process is moved back to the central office by using subcarrier multiplexing for fibre transmission. Instead of installing in remote node, ADSL/VDSL transceivers are installed at the central office to greatly reduce the remote node complexity. The local node simply down-converts the subcarrier multiplexed ADSL/VDSL signal to the baseband, suitable to send directly into the twisted-pair. The reduction of complexity could result in a lower initial installation cost, especially for a low service penetration rate. Copyright (C) 2000 John Wiley & Sons, Ltd.
