The design and performance of the hybrid access network for FTTH bottleneck areas

It is the development trend of the current carriers to enhance the rate of broadband services. The FTTx+VDSL2 access network is one of the best choices for the broadband access network, and migrating to the FTTH access network. It may be difficult to build the fiber into/in the house for some situation, such like the ful-filled line pipe and the decoration issues. The carriers have to introduce new methods or technologies for higher rate to form a hybrid access network in the FTTH bottleneck areas. In this paper, we had investigated the various technologies and architectures that could provide high speed access network and enlarge the coverage of the broadband service, including VDSL2 bonding, vectoring, G.fast, G.hn. Furthermore, we also proposed the test technologies and results to verify these technologies.
