Optical networks activity

The activity deals with the research and development of CEF networks, especially the data transmission methods, transmission equipment, first mile open-air transmission and cooperation on developing new applications using the GLIF (Global Lambda Integrated facility). The research results are being verified and deployed both in laboratory environments and in experimental wide-area networks, and consequently in production networks. Researchers together with designers and network operators in several countries, where the requirements differ significantly, verify the results. The Optical networks activity involves participation in the EU projects such as the GN2 – Multi-Gigabit European Academic Network (SA1, JRA3 and JRA4 activities), SEEFIRE, the CzechLight Extension international project (cooperation on research with hardware supplier), as well as participation in two grant projects.

GN2-SA1 activity Procurement attempts at finding new routes and technologies for the GN2 pan-European production network. The GN2-JRA3 activity investigates the current state and development of a connection-oriented, end-to-end (therefore multi-domain) bandwidth allocation and reservation service – in other words, a "Bandwidth on Demand" service. The GN2-JRA4 research activity gathers experience with new concepts of network building and interconnecting the European national test networks. It also aims at testing new transmission technologies for the GN2 network.

The EU SEEFIRE project is aimed at getting ready for future collaboration in the South-East Europe by producing a study on the availability of options for network infrastructure, as well as on possible strategies for Research and Education Networking development in the SE Europe. As a result, the SEEFIRE project will contribute to smooth introducing the SE European countries into the eInfrastructures community, it will allow for participating countries to pursue the forthcoming FP6 projects and to become more technologically competent in cooperating with the community. The technical core of the work involves the preparation of interurban and international dark fibre connections and a choice of an inexpensive and progressive technology for lighting them.

The CzechLight Extension international project attempts at extending the CzechLight experimental network both in the geographical and functional sense. Using the manufacturer's material support, Cisco transmission and switching facilities will be verified during the project and their applications tested.

The Czech Republic Grant Agency grant targets the Optimisation of data transmission at 10 Gbps over G.652 fibres with respect to maximum transmission distance without deploying in-line EDFAs.

Within the scope of the Information Society program, a numerical model of time division-multiplex (TDM) pumped Raman fibre amplifier will be developed and a sample TDM pumped Raman amplifier will be implemented
