Dark fibres in RENs are available More than 20 000 km in Europe
(plus some fibres for GN2 and GN2 testbed) About 33 920 km in USA
(including National LambdaRail) About 6 700 km in Canada
But: old and very expensive transmission equipment is mostly used

Demands on Equipment for CEF RENs Big differences from ISP (not for profit, known
users, SLA, experiments, ….) Universities, research organisations and NRENs
should prefer payment for research and education, not for network equipment
Distances between university premises are usualy short: In-line equipment in huts are not necessary
Low cost transmission equipment enables – networking in developing countries (solving of digital
divide),– new research directions, etc.

CESNET’s approach NIL for distances up to about 300 km Multiple long span (n x about 150 km) CESNET-made equipment based on available
optical devices and modules, SPF, XPF, interface cards, FPGA, etc. (for example PC Light 2in1, Combo6)
Testing in CzechLight, CESNET2 Prepared testing in other NRENs, GN2 testbed,
SEEFIRE project, …

NIL tests in laboratory G.652 fibre spools, EDFA + Raman:
325 km GE 250 km OC-48 252 km 2x 10 GE 290 km 10 G DWDM
G.655 fibre spools (EDFA + Raman): 302 km 10 G DWDM
Big differences betweenDesign, Simulation, Laboratory testing, Field testing

Research cooperation between CESNET and Lucent ?
• CEF Networks recognized as emerging market for transmission and switching equipment• CESNET recognized as leading organization in long-span CEF Networks deployment• Suggested goals of cooperation:
•Design of low costs transmission technology for CEF networks• User laboratory and field testing of Lucent equipment
