GPON unbundling for multioperator access

This work aims at considering different unbundling options for the Local Loop Unbundling (LLU) in order to provide multi-operator access and consider the economical impact for the FTTH NGA entrants to deploy such alternatives. We show that deploying WDM networks is an efficient strategy to perform LLU while upgrading the GPON network for the new era where high bandwidths are necessary for satisfying customers' demand. In areas with high population density, WDM techniques are the most suitable for entrant operators to access the incumbent's network and provide service.
