Evolution of FTTH networks based on radio-over-fibre

In this paper we review and compare the current gigabit passive optical networks (GPON) fibre to the home (FTTH) based solution, and discuss an evolution scenario to future next generation PONs (XGPONs) and wavelength division multiplexing PONs (WDM-PONs) from an operator point-of-view, i.e., taking into account standardization, wavelength planning, optical line terminal as well as optical network terminal equipment and transmission convergence layer. We also compare proposed solutions for the provision of quintuple play services over orthogonal frequency division multiplexing (OFDM) in several aspects such as equipment requirements, capacity to the end user and limitations.
