Abstract

We have studied a novel optical access network with PLZT (Plomb Lanthanum Zirconate Titanate) optical switches, called ActiON (Active Optical Network), as a next generation access network to replace PON (Passive Optical Network). On the other hand, energy consumption of the present network becomes an important problem today. To resolve this problem, we study an energy efficient metro-access hybrid network by using ActiON. Also, it is necessary to extend a bandwidth capacity of ActiON to realize a scalable network. In this paper, we mainly focus on an energy consumption and a scalability. As a result, the proposed next generation metro-access hybrid scalable network accommodates 600000 users. In the evaluation, we show that proposed network reduces 65 % of energy consumption compare to the present network. Furthermore, blocking ratio of proposed network is lower than a quality assurance of the Internet service in any cases.
