Common Fibre Optic Infrastructure Strategies

LuxConnect is a private limited company setup in January 2007 The mission of LuxConnect To promote and facilitate high level ICT invests in Luxembourg Objectives Raising Luxembourg on International Internet “maps” “State of art” space available in Data Centres Interlinking countries Driver New economical pillar inside Luxembourg

Luxembourg is connected to the German grid (Amprion) via two double HV lines The Gas Network from Creos is interconnected to the German, French and Belgian Networks. Transport Network High Pressure (HP) : 60-80 bar Distribution Network Medium Pressure(MP) : 0,1-1 bar Low Pressure(BP) : 0,01-0,1 bar High Voltage to High Voltage from 220 kV to 65 kV 5 stations High Voltage to Medium Voltage from 65 kV to 20 kV 48 stations over Luxembourg Medium Voltage to Low Voltage from 20 kV to 0,4 kV 2 428 stations

? Drivers Interconnecting as many as possible MV stations No contiguous network-Hundred’s of segments Cost effective solution Accelerated rollout ? “Red” network realized – “Green” network projected Cost effective solution Accelerated rollout

- National fiber Network ( Dark fiber) - > 850km of fiber optics - All kind of school and municipality buildings connected - Collective antenna sites connected - Nationwide interconnection of all Data Centers - Competitive development of dark fibre offer Actual Duct system: (only related to MV projects) 277 km of tubes 125/110mm Only segments 60 km of tubes 32mm installed (inside 125/110mm) 56 km of tubes 50mm along the Gas network 0 Stations MT/Gas interconnected via fibre optic

Overall beginning A B Projected link LuxConnect MV MV A B MV Projected link LuxConnect Existing Segments from Creos MV Medium Voltage stations Projected Manholes

The solution 1/2 Creos implements in his segments a flatliner in existing ducts, or in newer projects only a flatliner LuxConnect implements in his segments a flatliner 125/110mm Creos implements in the last mile sector a smaller flatliner 125/110mm

The solution 2/2 Creos implements only fibre optics in the last mile sector LuxConnect is renting from Creos a third of their tubes ex. orange colored, implements their fibres optics Costs: 1m of tubes = 2m of 12 fibres optics LuxConnect implements manholes with their splice box Creos enters in the same manhole with his own splice box for being interconnected to the 12 fibres in the backbone on one hand and on the other hand managing his last mile

The result A B Backbone LuxConnect MV MV A B MV Backbone LuxConnect 12 fibres optics due to renting used by Creos Remaining meters due to Creos from another part of the network Last mile of Creos MV Medium Voltage stations Manholes

The reality LuxConnect Backbone Creos Last Mile

Case study 1 Inside 5 years Creos fully deploy a F.O. network Calculation base: 1500 MV stations and 1300 km F.O. Costs: Tubes 125/110: 1200km = 96 M€ (80€/m) Tubes 32mm: 1200 km = 6 M€ (5€/m) Manholes etc : 1.2M€ MV connection: Tubes 225km = 15.6 M€ (65€/m via particip.) Manholes etc. 1500 = 4.5 M€ Fibre optics: Backbone: 1300km = 19.5 M€ (15€/m) MV level: 225km = 3.375 M€ (15€/m) Housings, Connecters etc. = 2 M€ FTE: at least 3 suppl. au Comin and suppl. Work for Project Manager Total : = ~150 M€ (with « flatliner » – 8 M€) Inside 5 years ( for covering 3000 MV stations with 4500 km of F.O. around 500M€)

Case study 2 Total : = ~35 M€ Creos and Luxconnect : Calculation base: 1500 MV station et 1300 km of F.O. Costs for Backbone: « flatliner » 550km = 16.5 M€ (30€/m) Right on 1300km of F.O. inside a 1500km network of Luxconnect MV connection (last mile): (only Creos) Tubes 225km = 15.6 M€ (65€/m via particip.) Fibre optics: Backbone: 1300km = 0 M€ Last mile MV: 225km = 0.9 M€ (4 €/m) Housings, Connecters etc. = 2 M€ FTE: 1 suppl. at Comin and less suppl. Work for Project Manager Total : = ~35 M€

Conclusion 5 years of invest in Backbone (Creos -> LuxConnect) 15 years of invest in last mile (MV to backbone, Creos) 1500 Creos MV stations interconnected - used backbone 1300km at LuxConnect - last mile 225km Faster rollout of the fiber network (LuxConnect) Less cost intensive (LuxConnect and Creos)
