Paper Abstract

With the development of Internet application, user needs more and more bandwidth. 10G EPON is a good choice for next generation access-network. The architecture of the WDM-based 10G EPON is proposed in this paper and we also provide the configuration of the upstream. WDM-based 10G EPON operate in different speed on different direction, and the logical link is point to point communication in the upstream while behaving as multipoint to point in physical topology. We put forward the protocol stack of this architecture. We proposed a sub-layer named MWMC (Multi-Wavelengths MAC Control). The MWMC sub-layer need not deal with Timing, Ranging, Report or Gating processing. But LLID (Logical Link Identifier) is also needed to implement the P2PE (Point to Point Emulation) in the downstream. We detailed dissertate how to implement the P2PE in this architecture using the concept of LLID. The WDM-based 10G EPON is easy to implement and need not high speed burst mode transceivers, and its cost is not very high. The WDM-based 10G EPON has better performance than the TDMA-based 10G EPON for its low delay and high upload bandwidth with no collision between different ONUs in the upstream.
