This paper proposes an optimum multicast time slot allocation scheme in the active optical access network. The proposed scheme combines multi-level modulation and distribution mode that optical switch acts like optical coupler.
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...
