Future passive

The evolution of fibre networks has led to increased bandwidth, which in turn has enabled new services, but this growth in the network has not translated into a proportional growth in revenue for operators. To attempt to remedy this unsustainable situation, several European research projects have been set up to investigate new technologies for optical access networks.
