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, …

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
