CESNET

 The CESNET (Czech Educational and Scientific

Network) association was formed by the Czech universities (27) and Academy of Sciences of the Czech Republic in 1996

 Non-profit organization, funded by Ministry of

Education of the Czech Republic, association members and external sources (EU)

 First ISP in Czech republic  Now pure academic network  More details on www.ces.net

CEF Approach

Customer Empowered Fiber (CEF) concept

  • Leased dark fibers equipped by own transmission

technology

  • The first lines enlighted in 2000 (PoS STM-16 and

1 GE lines)

  • Standard SMF G.652 and NZDSF G.655 fiber

types

  • About 5,000 km of leased dark fiber lines

CEF Approach

 Mostly the whole backbone on CEF  Both single-channel and DWDM  Cost effective solution on speed 10Gb and above  CBF – Cross Border Fiber  Commercial equipment and Cesnet developed

devices
