Abstract
We propose and demonstrate a RN (remote node) architecture that enables direct ONU (Optical Network Unit) internetworking within a group and/or with another groups by using FBG (Fiber Bragg Grating) array in TDM-PON (Time Division Multiplexed Passive Optical Network). The specific wavelength assignments are used for the traffic intended for various virtual private groups and for overall broadcasting. The proposed architecture supports downstream, upstream and direct inter-ONU transmission simultaneously. Direct inter-ONU communication reduces the power consumption and transmission latency during communication among nearby located ONUs. To check the feasibility of the proposed architecture, its performance is verified with the simulation results using Optisystem 13.0.
