  1. CzechLight testbed Lada Altmanová Jan Radil Stanislav Šíma Josef Vojtěch GN2 APM meeting, Prague February 24th, 2005

  2. Global Lambda Integrated Facility (GLIF) • Environment for co-operation: networking, infrastructure, network engineering, system integration, middleware, applications • GLIF was established by invited participants at the 3rd Global Lambda Grid Workshop, held August 27, 2003 in Reykjavik, Island, www.glif.is • Dark fibres are often used for Gigabit or 10 Gigabit access to cities and university premises CzechLight Testbed

  3. GLIF – World Map December 2004 CzechLight Testbed

  4. CzechLight connections (to GLIF, to GN2 testbed and to cz premises) CzechLight Testbed

  5. CzechLight Testbed

  6. CzechLight intercity connections • Prague – Amsterdam lambda (GLIF facility), first mile in Prague on dark fibre, OC-192c transmission, grey 1550nm • Prague – Brno, dark fibre, 298.3 km, 66,5 dB, including 257.3 km of G.655 fibre, DWDM OC-192c transmission, NIL test • Prague – Plzen, dark fibre, 159.4 km, 36.7 dB, GE transmission by PCLight EDFA 2in1 CzechLight Testbed

  7. CzechLight connections in/near Prague • Connections of Particle physics workplaces - Institute of Physics of the Academy of Sciences of theCzech republic, dark fibre, GE transmission - Faculty of Mathematics and Physics of Charles University, dark fibre, GE transmission - Nuclear Physics Institute of the Academy of Sciences of the Czech Republic in Řež, dark fibre, GE transmission - Faculty of Nuclear and Physical Engineering of Czech Technical University, lambda on PASNET dark fibres by CWDM, GE transmission CzechLight Testbed

  8. City dark fibre lines to the of CzechLight node in Prague CzechLight Testbed

  9. CzechLight configuration • Core node in Prague CISCO 15454 with 10 G DWDM SONET, 4xGE CISCO C3550 – 12G CISCO C6503 with 10 GE and GE • Core node in Brno CISCO 15454 with 10 G DWDM SONET, 4xGE CzechLight Testbed

  10. PC Light • Design Kit for wide area fibre networks, based on racked PCs with build-in optical amplifier modules • Multi-vendor (multi-source) building elements • Preliminary comparison of OA (EDFA) costs: • OA from „ISP vendor“: 40 000 USD • OA from „optical vendor“: 18 000 USD • OA from „module vendor“: 2 500 USD (two OA in module) • OA from Integrated Circuit vendor: 2000 USD/pc • OA + DCF costs are the biggest item in long distance transmission systems costs (e.g. 60%) => PC Light helps to radically change WAN/MAN costs CzechLight Testbed

  11. EDFA 2in1 v2.0: PC Light equipment example • PC with build-in OA EDFA booster and preamp • Successfully used for NIL GE connection from Plzen to CzechLight in Prague by dark fibre pair (159.4 km, 36.7 dB) since May 2004 • One Side Amplification (OSA NIL approach): this equipment is placed in Prague only. No OA equipment is placed in Plzen, so we expect lower service costs and higher availability (we have 24/7 staff in Prague only) • Advantages: low cost, small size (1U), redundant PSU, low power consumption, Linux, SNMP, reach up to 225 km, extensive management possibilities (Ethernet, GSM modem, BlueTooth, RS-232,…) CzechLight Testbed

  12. Alarm LEDs Low NF preamplifier PA IN PA OUT BO IN BO OUT Flash disc* Booster +5V DC IDE RS 232 Power Supply MicroATX MainBoard with fanless CPU FE USB * Network boot is also possible RS232C EDFA 2in1: EDFA Module in Standard 1U PC with Linux CzechLight Testbed

  13. PC Light forthcoming • EDFA 2in1 tested in lab and production environments • PCLight Raman (fibre or diode) • SOA amplifiers • 1310 nm and 1550 nm • Even true broadband (100 nm) amplifiers for MAN CzechLight Testbed

  14. Lighting of dark fibre: NIL update • Production lines G.652, 1550 nm, EDFA • 189 km Praha – Pardubice GE since May 2002 • 235 km Brno – Ostrava GE since June 2003 • Experimental lines G.652, 1550 nm, EDFA • 235 km Brno – Ostrava OC-48 June 2003 • 286 km Praha – Brno GE May 2004 (+Raman) • More wavelengths possible CzechLight Testbed

  15. NIL tests in laboratory • G.652 fibre spools, EDFA + Raman: • 325 km GE • 250 km OC-48 • 252 km 2x 10 GE • 302 km 10 G DWDM • G.652 + G.655 fibre spools, EDFA + Raman • 302 km 10 G DWDM CzechLight Testbed

  16. Acknowledgement • Jan Gruntorad for support and GLIF entry • Miroslav Karasek for lighting of CESNET2 and CzechLight fibres • Comment: presented ideas and opinions are result of our ongoing R&D activities and are opened to improvement CzechLight Testbed
