The FLIPER proposal aims at the definition, study and realization of a new fully scalable and flexible optical access network significantly extending the network dimensions in one order of magnitude, in terms of bandwidth utilization, distance and number of multiplexed users in a dynamic form. The envisioned access network evolves from the almost-commercial TDM/WDM-PON architectures to the realisation of the Ultra-Dense WDM solutions, opening the way to the wavelength-to-the-user concept. This enables a user to enjoy a flexible individual bandwidth from the Mbit/s to 10 Gbit/s flexibly, making an elastic usage of the optical spectrum. The key enabling technology will be a new cost-effective coherent detection scheme with reconfigurable transceivers, managing a Flex- Grid optical spectrum elasticly. This will allow for the first time to leverage effective coherent terminals suitable for mass deployment adaptable to the future user bandwidth and service demands. Although conceptually complex, these terminals must be compatible with the cost levels typical of low-cost consumer electronics, thus affordable to the end-users. Therefore FLIPER can drive the realization of flexible and bandwidth-efficient next-generation access networks, compatible with the existing PON infrastructures. As a result, high speed connections will be available to the common users, thus opening the way to a huge potential of application and socio-economical developments.
