It operated global network routes on self-healing rings in North America, Europe and Asia including submarine communications cable systems in the North Atlantic Ocean which connected Canada, the United States, the Republic of Ireland, the United Kingdom and mainland Europe. Hibernia managed cable landing stations in Dublin, Republic of Ireland; Coleraine, Northern Ireland; Southport, England; Halifax, Canada; Lynn, Massachusetts, United States.

Hibernia's network provided service, from 2.5 Gbit/s to 100 Gbit/s wavelengths and Ethernet from 10 Mbit/s to 100 Gbit/s. It also provided traditional SONET/SDH services.
