Techno-economical Comparison Between Gpon And Epon Networks

Taking in consideration two leading high capacity optical access technologies, this paper presents a simple cost comparison between GPON and EPON platforms, exposing their major characteristics, making a comparative analysis to find the advantages and disadvantages between these two technologies. The work includes studies on the economic and technical feasibility of implementing a passive optical network; and the choice of valid economic and technical arguments when establishing, planning, or expanding such networks in a given region. The techno economic balance today clearly points to GPON technology, despite the high volume of IP-Ethernet data traffic which favors EPON. © 2009 ITU.201205IEEE Communications SocietyRamaswami, R., Sivarajan, K.N., (2002) Optical Networks: Practical Perspective, , Morgan Kaufmann, Academic Press, BostonGrady, S.C., (2005) The book on FTTX From Design To Deployment: A Practical Guide To FTTX Infrastructure, ADC Telecommunications, , USAhttp://www.ftthcouncil.org, FTTH Council [Online, AvailableBarbosa, F.R., Novel Optical Switching Architecture for Metropolitan Photonic Networks (2005) II OSAChapter Workshop on Optical Comm, , paper Fri-01, São Paulo, Brasil, NovITU-T Rec.
