This class will introduce to the Internet access technologies – including transmission techniques -- exploiting the photonic infrastructure according to the fiber-to-the-home or fiber-to-the-cabinet paradigm. So, the anyzed networks extend are limited to few tens of kilometers. State-of-the-art and near future evolutions will be introduced with special attention to 5G-related technologies. Potentialities and criticalities on possible time distribution to the final user will be addressed.
