New Nationwide network 2016 3 fiberpaths to all regions Improved redundancy 15 year IRU Possibility to connect customers at ~50 sites (with smaller modifications ~80 more) Cross border fibers at: Kiruna-Narvik Luleå-Kemi Malmö-Copenhagen Leased capacity to Gotland (Visby)
Fiberplant Core fibers mostly Aerial in high voltage power lines New and old fibers, G.652B some G.652D OTDR and attenuation data delivered as they measured Kmz data Access fiber from city networks Two separate paths to university No KMZ data
A (new) way of building networks IP over DWDM (IPoDWDM). Eliminates unnecessary and expensive components => less components that fails Reroute traffic before fail Much lower CAPEX but also lower OPEX Gridless The worlds first nationwide network using this technology
