Metropolitan area network
Porto Digital owns and manages a Metropolitan Area Network (MAN), which covers most of the city of Porto. It is an optical fiber communications infrastructure, which provides low-cost and free broadband connection to several sites at the city, in particular, to the Municipality of Porto, local administration companies and authorities, hospitals, universities and polytechnic institutes, R&D facilities, museums, the police and other public institutions.
The MAN comprises a backbone, a distribution network and an access network. The backbone comprises a ring network made of 48 fibers with a length of 23 km and 5 points-of-presence (PoPs), and has a 10 Gigabit Ethernet connection. The distribution network comprises 9 sub-rings with a length of 89 km, and has a 10 Gigabit Ethernet connection. The access network connects 245 sites, has a length of 83 km of fiber and has a up to 1 Gigabit Ethernet connection. The network has a high degree of redundancy and is equipped with IP/MPLS/VPLS equipment.
Between 2003 and 2008, Porto Digital designed and deployed the most significant part of the network, which was co-financed by the European Regional Development Fund (FEDER) and national funds
