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)
