10th CEF Networks Workshop 2019

Quick navigation:

The 10th Customer Empowered Fibre Networks Workshop shall be held in Prague from September 3rd to 4th. Major topics for this year event are:

  • Rapidly developing applications of photonic or dark fibre connectivity (cryptography, metrology, seismology, space, observation, sensor networks, etc.)
  • Photonic (all-optical) services, spectrum sharing, dark fibre channels, alien waves, fibre sharing, optimal or dynamic usage of transmission spectrum and virtual fibre networks
  • SDN approach and end to end services for high precision and high bandwidth, performance applications, real-time applications of wide-area all-optical networks
  • Multi-vendor/disaggregated lighting of CEF networks, interoperability and vendor-independent description of transmission systems
  • Dark fibre or channel test-beds and experimental facilities (in campuses, regional, national or continental) used for experiments and additional production traffic
  • Deployments and testing of high-speed transmission systems, power consumption of transmission systems(greening)
  • Development of dark fibre footprint used for Research and Education
  • Research and Education community in Asia, Australia, North America, South America and Europe
  • Improvement of long term Research and Education community economy


Registration is closed.

Masaryk Dormitory, CTU in Prague,
Thákurova 1, Prague 6

How to get there

The location of Masaryk Dormitory is really suitable. There is a good connection from/to the airport in less than 30 minutes. When using public transportation, bus 119 plus metro, or tram is available. See the .

From the airport:
Bus no. 119 (stop is in the middle of the car park outside the arrival hall, just walk straight and look for the signs) will take you to the Metro station “Nadrazi Veleslavin” (15 minutes). Bus 119 ends here, so don’t worry. Change to Metro (subway) and go two stations in direction “Depo Hostivar” to the station “Dejvicka”. The bus comes quite frequently—see the time table. You have to buy a general public transport ticket and stamp it inside the bus. The tickets are sold at yellow vending machines in all metro stations or tram stops and newspaper kiosks for 32 CZK (about 1.2 Euro).
From anywhere else:
Use subway (Metro). Go to the line A and then to the Dejvicka station. Plans of Metro lines are available on stations and inside trains (above every door).
