Techno-economic analysis of PON architectures for FTTH deployments: Comparison between GPON,XGPON and NG-PON2 for a Greenfield operator

In this paper the cost for the deployment of a PON FTTH network is calculated in terms of NPV, IRR and payback period. A comparison is made between three PON technologies: GPON, XGPON and NG-PON2. Different scenarios regarding population density and bitrates are examined. It is shown that for high data rate scenarios in areas with high population density NG-PON2 can become a viable and future proof alternative to GPON and XGPON.
