Abstract :
In this paper, we design and evaluate through modelling a solution for 10/1 Gb/s asymmetric EPON upgrade using simple active remote node that is capable of supporting layer two filtering scheme. The remote node learns information on connected ONUs and filters unwanted frames to keep the ONUs´ transceiver ports at 1 Gb/s while upgrading only the feeder link between OLT and RNs to 10 Gb/s to reduce the initial capital expenditure of deploying 10 G-EPON system. Using numerical modelling, we analyse an EPON system consisting of 160 ONUs implemented with a dual splits of 1:10 and 1:16. The results show that the proposed EPON with remote node upgrade solution is capable of achieving same downstream data rate compared to point-to-point full 10 Gb/s upgrade while offering significant reduction in initial upgrade cost.
