Descripción del proyecto
PIEMAN will perform ambitious physical layer research into a future broadband optical access system with capability well beyond what is achievable today. The objective is a 100 km reach photonic network which will integrate access and metro into one system, whereas today access and metro are provided by separate systems. PIEMAN will therefore greatly simplify network architectures and so reduce costs. The PIEMAN system will be an evolution from todays passive optical networks and will offer multiple wavelengths each carrying 10 Gbit/s upstream and downstream. The upstream direction is especially challenging at 10 Gbit/s: a factor of ten faster than any passive optical network to date. The system will be all-optical between the user and the service node ~100 km distant. Radical new techniques will be studied to allow cost-effective, tunable wavelength 10 Gbit/s transmitters in the customer premises.
