Metropolitan Area Networks


A Metropolitan Area Network (MAN) is a network that consists of telecoms ducting and fibre optic cable.  It is laid in a ring formation in a metropolitan area.  The network connects to "co-location centres". 

In these co-location centres, licenced telecoms operators can locate their telecommunications equipment and link to commercial premises and public buildings.  The MAN can be used to provide a variety services. These include telecoms, Internet access, television and closed circuit television (CCTV) to businesses and citizens in these areas.

The MANs

  • Are publicly owned;
  • Allow wholesale and open access to all licenced telecommunication operators; and
  • Are fibre-based, technology neutral resilient networks.

    The MANs were funded under the National Development Plan and through the European Regional Development Fund. There were 2 Phases to the building of MANs -
  • 28 MANs were completed under Phase 1
  • 60 MANs were completed under Phase 2

MANs are independently managed, maintained and operated for the State by a Management Services Entity (MSE). enet were awarded a 15-year services contract in June 2004. In July 2009, they were awarded a 15-year services contract to operate and manage the Phase 2 MANs.  For further information on how the MANs operate you can visit
