Dark fibres in European NRENs
3The Quilt's 2007 Spring Member Meeting and Workshop
Why dark fibresfor Research and Education Networks (RENs)?
(this slide we have published in TNC2004, Rhodes)
Freedom in REN design
Fixed costs of long-term use Transmission capacity up to Tbps Cost-effective ways of sharing (WDM, TDM, …) Multiple wavelengths possible (e.g. 1 – 256) Management of transmission Equipment selection, moving, design, …..

4The Quilt's 2007 Spring Member Meeting and Workshop
Moving RENs to dark fibres since 1999 Moving of Research and Education Networks to dark fibres is
successful and continues:– CESNET, DFN, GRNET, Pioneer, RENATER, SANET, SURFNET,
SWITCH…
– Regional Optical Networks in US
– Continental-wide RENs: NLR, GEANT2, Internet2
– NRENs with long distances (Nordunet 2006-2007)
– South East European countries (SEEFIRE and SEEGRID2 projects)
– Baltic, East European and Southern Caucasus countries (POS project)
Some other networks follow RENs (municipalities, hospitals, enterprises, … )

First dark fibre line in CESNET Praha-Brno 323 km since1999, operational since
January 2000 Contract with fibre owner company- oil transit company Subject of contract is research cooperation (evaluation
of some new usage possibilities, etc.). Fibre line Praha-Brno was operational in CESNET
before telecom market liberalization in the Czech Republic

Leased Dark Fibres in CESNET
1999 : 323 km 2003 : 2.470 km 2007 : 4.830 km
(including 370 km of single fibre lines)
CESNET has 26 members.
We connect 45 university cities in the Czech Republic.
Population : 10,272.503
Area : 78.864 square kilometres = 30.450 square miles
(approximately as South Carolina or Maine)

Typical prices of leased DF in CESNET
0.1 – 0.5 Euro/m/y – pair of fibres (fibre lengths from 30 km to 323 km)
0.3 Euro/m/y – one fibre (fibre lengths from 34 km to 126 km)
Lease contracts are mostly 4 years with prolongation option, O&M included
Best prices were acquired for DF between big cities, for long distances and for longer contract periods
Comparison: 0.13 Euro/m/y is Fiberco Price of strand pair for 20 year IRU (source: FiberCo/WaveCo Update, Joint Techs, Minneapolis, February 12, 2007)

Cross Border Dark Fibres (CBFs)started in 2002
Neighbour NREN fibre footprints can be connected by short dark fibres
CBFs allow connection of NRENs as cellular structure instead of legacy overlaying connection
CBFs are usually short, non-expensive and carry high traffic between neighbour NRENs
CBFs save expensive long distance capacity services going via central PoPs of NRENs

CBFs operational since 2002 GE lighting
– Bratislava (SK) – Vienna (AT) since 2002, 104 km
– Brno (CZ) - Bratislava (SK) since 2003, 182 km
– Ostrava (CZ) - B. Biala (PL) since 2004, 117 km
10GE lighting– upgrade of Brno (CZ) - Bratislava (SK) since 2005, 8x10G WDM
– Ostrava (CZ) - Cieszyn (PL) since 2006, 75 km, 32 x 10G WDM
– Bratislava (SK) – Vienna (AT) since 2006
– Brno (CZ) – Vienna (AT) since 2006, 224 km, 8 x 10G WDM, creating first cross border dark fibre triangle (Brno-Bratislava-Vienna-Brno)
NRENs and regions moving to dark fibres since 2005 use CBFs

B&H dark fibre plan
September 2006: SEEREN2 is the first EU funded regional project that builds international cross border link based purely on dark-fibre services. Link to provide connectivity to 3 or more universities in B&H

GÉANT started dark fibre use since 2005
GÉANT2 uses dark fibre connection of GÉANT PoPs located in NREN central PoPs (usually in capitals)
All GÉANT2 dark fibres are crossing borders, distances are about 110 – 3000 km, but are not called CBF (CBF should be short connection between neighbour NREN PoPs close to border)
GÉANT dark fibre footprint is overlaying national dark fibre footprints

GÉANT2 Co-funded by the
European Commission (up to 50%) and Europe's national research and education networks and is managed by DANTE
30 European NRENs
12,000 km of DF 200 sites 18 DF routes 26 leased SDH

GEANT2 started CBF use since 2006 CBFs are installed by NRENs and used for GÉANT2 lambda
services (in part or fully) Motivation:
– Installing of cost-effective lambdas to GÉANT2 PoPs for which not available GÉANT2 dark fibres (for example Poznan)
– using optimal connections for some important projects (ATLAS)
CBFs used for GÉANT2 – Frankfurt/Oder (DE) – Slubice (PL)
– Como (IT) – Manno (CH)
– Basel (CH) - Kehl (DE)
– Kehl (DE) – Strasbourg (FR)
– Enschede (NL) - Münster (DE)
