基于VDSL2和VLC的用户接入网系统设计及实现
Design and implementation of subscriber access network system based on VDSL2 and VLC
摘要
Abstract
This paper presents a novel subscriber access network system based on very high-bit-rate digital subscriber line(VDSL2) and visible light communication(VLC), the system uses VLC ring link instead of tra-ditional twisted pair in VDSL2 system, the paper designs a new business model of VDSL2 access network system to realize wireless transmission between VDSL2 master-slave devices. The paper fabricates experi-mental device, tests and analyzes the VLC amplitude frequency characteristics, the feasibility of master-slave device connections, the transmission rate, and the change of communication rate in different signal strength condition. The experimental results demonstrate that network connection is established under short distance testing conditions, and the total uplink-downlink rate can reach 41Mb/s, it indicates the feasibility and appli-cability of the designed system.关键词
