Abstract:
Likely unique in Europe, due to its own peculiar service delivery paradigm Lepida, the network of the public government organizations of the region Emilia-Romagna, in the north of Italy, chooses a passive Wavelength Division Multiplexing (WDM) fiber access technology. Passive WDM deeply exploits the frequency domain in order to multiplex multiple signals in the same optical fiber. In particular, a full Coarse WDM (CWDM) approach, deployed in a pre-existent network, can increase reliability, bandwidth, security and configuration cleanliness in a pay-as- you-grown way. In this paper, we present benefits, costs, pros and cons, and how we achieve them, of an interesting concrete implementation of WDM fiber access technology in a wide and complex territory.
