Design and implementation of the broadband network access system over MoCA

In order to provide a high speed scheme for the access of the "last 100 meters", a composite access scheme of EPON and MoCA is proposed in this paper. At the terminal node of FTTX in EPON system, MoCA technique is used to implement broadband data access by distributing network entering household through Coax. A terminal equipment is designed in this scheme, which can receive the optical signal from the OLT of EPON and transform it into RF signal. The end users will receive the RF signal either from the coaxial cable or a RF antenna. This scheme is particularly applicable for FTTB application.There are many advantages in this system, it can provide a reliable room to room, peer to peer full mesh connectivity of digital content among MoCA devices using existing in-home coaxial cables. Plug and play at the majority of serviceable coax outlets in homes with no need to access or change splitters, or run new cables. What's more, it has higher bandwidth and better management. Two group of tests for the EPON+MoCA system were carried out, one for the coaxial cable and one for wireless. The experimental results showed that the average throughput of the system could reach to approximate 100 Mbps which approach to the theoretical throughput of MoCA 1.0 standard. And the transmission throughput had no remarkable change when the RF antenna replaced the coaxial cable.
