Recent optical technologies are providing higher flexibility to next generation access
networks: on the one hand, providing progressive FTTx and specifically FTTH deployment,
progressively shortening the copper access network; on the other hand, also opening fixed-mobile
convergence solutions in next generation PON architectures. It is provided an overview of the
optical subsystems developed for the implementation of the proposed NG-Access Networks.
