Abstract :
The purpose of this article is to provide an overview of some system aspects allowing full service deployment over hybrid fiber-twisted pair access networks with a VDSL drop. Although VDSL and ADSL systems are similar from the point of view of transmission technology, there are differences in the architecture and implementation due to both the higher bandwidth and shorter copper loop length for VDSL. The VDSL drivers are given in the introduction. The next section describes the system architecture and the functionality of the various building blocks. Special attention is paid to optical feeder technology, for which APON is a well-suited technology. Concepts to reduce the cost of ownership are also discussed
