1 CESNET Research Department CEF Networks lighting: search for equipment Stanislav Sima November 23th, 2004

2 CESNET Research Department Equipment for CEF Networks Prague November 23th, 2004Lucent meeting 2 Dark fibres in RENs are available l More than km in Europe (plus some fibres for GN2 and GN2 testbed) l About km in USA (including National LambdaRail) l About km in Canada But: old and very expensive transmission equipment is mostly used

3 CESNET Research Department Equipment for CEF Networks Prague November 23th, 2004Lucent meeting 3 Demands on Equipment for CEF RENs l Big differences from ISP (not for profit, known users, SLA, experiments, ….) l Universities, research organisations and NRENs should prefer payment for research and education, not for network equipment l Distances between university premises are usualy short: In-line equipment in huts are not necessary l Low cost transmission equipment enables –networking in developing countries (solving of digital divide), –new research directions, etc.

4 CESNET Research Department Equipment for CEF Networks Prague November 23th, 2004Lucent meeting 4 CESNET’s approach l NIL for distances up to about 300 km l Multiple long span (n x about 150 km) l CESNET-made equipment based on available optical devices and modules, SPF, XPF, interface cards, FPGA, etc. (for example PC Light 2in1, Combo6) l Testing in CzechLight, CESNET2 l Prepared testing in other NRENs, GN2 testbed, SEEFIRE project, …

5 CESNET Research Department Equipment for CEF Networks Prague November 23th, 2004Lucent meeting 5

6 CESNET Research Department Equipment for CEF Networks Prague November 23th, 2004Lucent meeting 6 CzechLight structure and connections

7 CESNET Research Department Equipment for CEF Networks Prague November 23th, 2004Lucent meeting 7 Lighting of dark fibre: NIL approach l Production lines G.652, 1550 nm, EDFA 189 km Praha – Pardubice GE since May km Brno – Ostrava GE since June km Brno – Ostrava OC-48 in 4 months 2004 l Experimental lines G.652, 1550 nm, EDFA 160 km Praha – Plzen GE April 2004 PC Light (one side) 286 km Praha – Brno GE May 2004 (+Raman) l Experimental line G.655+G.652, 1550 nm, EDFA 298 km Praha – Brno 10 GE November 2004 (+Raman) l More wavelengths possible

8 CESNET Research Department Equipment for CEF Networks Prague November 23th, 2004Lucent meeting 8 NIL tests in laboratory l G.652 fibre spools, EDFA + Raman: 325 km GE 250 km OC km 2x 10 GE 290 km 10 G DWDM l G.655 fibre spools (EDFA + Raman): 302 km 10 G DWDM Big differences between Design, Simulation, Laboratory testing, Field testing

9 CESNET Research Department Equipment for CEF Networks Prague November 23th, 2004Lucent meeting 9 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

10 CESNET Research Department Equipment for CEF Networks Prague November 23th, 2004Lucent meeting 10 Acknowledgement l Jan Gruntorad for support and GLIF entry l Lada Altmanova for dark fibre acquiring l Miroslav Karasek and Jan Radil for lighting of CESNET2 and CzechLight fibres l Comment: presented ideas and opinions are result of our ongoing R&D activities and are opened to improvement
