Concept of Customer Empowered Networks

- more flexibility for the „Customer“

- more cost effective

- access to dark fibres essential

1999

Telecom market situation in CZ - offer much higher than demand

Convinced one company (MERO) lease dark fiber between Praha – Brno for pilot project.

Prague-Brno circuit capacity 2,5 Gbps

Last (First Mile Issue)

- concept of „meeting“ point

- joined investment of fiber provider, CESNET and local organization to fiber between „meeting“ point and CESNET PoP location

Praha – Pardubice Long distance GE line

Praha – Pardubice (Long distance GE line since May 17, 2002)

• 189 km leased fibre G.652, attenuation 44.65dB, without in-line equipment• Traffic statistics: http://www.cesnet.cz/provoz/zatizeni/• Line cards: GE for GSR with GBIC-ZX• Optical amplifier: Keopsys KPS-BT-C-21-Bo-FA 21dBm booster• Optical attenuator: 5dB (for optical amplifier input)

Recomended applications for GE speed

• Booster only - up to 180km

• Booster with preamp - up to 220km• Booster with preamp and Raman - up to 270km
