Abstract

Metro-access network is a newly emerged network which combines the traditional separated metro network and access network together into a converged system. It serves more users in a larger geographical area, meanwhile maintaining a simplified network hierarchy which inherits the low cost, large bandwidth, and high reliability of PON. In this paper, a novel remote node for metro-access converged network is proposed, which supports multi-type PON colorlessly, meanwhile maintains single specification for all subscribers. In addition, it saves nearly half of the spectrum resource in the metro part.
