CzechLight and PCLightCzechLight • Experimental network (independent on production IP network - CESNET2) • Today – one Cisco ONS 15454 in Praha 2,5 Gb/s circuit to Amsterdam (NetherLight) • Upgrade to 10 G with another 15454 in Brno • Upgrade of Amsterdam circuit to 10G Klub ředitelů

CzechLight and PCLightCzechLight – research into practical live • Effort to transform results of network research to support CzechLight • Deployment of WDM/DWDM NIL 1 GE and 10 GE transmissions • Deployment of results of PCLight • Potential utilization of results of the Liberouter project – www.liberouter.org (1 GE and 10 GE interface cards, repeaters, transponders,…) Klub ředitelů
CzechLight and PCLightNIL transmission -practical results • Experimental NIL lines G.652, 1550 nm, EDFA • 235 km Brno – Ostrava OC-48 June 2003 • 286 km Praha – Brno GE May 2004 (+Raman) • NIL tests in lab, G.652 fibre spools, EDFA + Raman: • 325 km GE • 250 km OC-48 • 2 x 1 GE plus 2 x 10 GE over 202 km • 252 km 2x 10 GE • 290 km 10 G DWDM Klub ředitelů
CzechLight and PCLightPractical results – map of the Czech republic • 2 x 1 GE plus 2 x 10 GE over 202 km • 2 x 10 GE over 252 km • Air distances Klub ředitelů
CzechLight and PCLightPractical results – map of the Czech republic • Correcteddiameters • Air to fibre distance ratio – AFDR • AFDR = 0,65 (example of bad case) Klub ředitelů
CzechLight and PCLightPCLight • Lets connect by cost effective way who needs it • Racked PC = fast development + good reliability • Design kit for wide area fibre networks, based on racked PCs • Start with OA - OA cost is biggest item in long distance transmission systems cost (e.g. 60%) Klub ředitelů
CzechLight and PCLightEDFA 2in1 - PCLight equipment example • PC with build-in OA EDFA booster and preamp • Successfully used for NIL GE connection Plzen to Prague by dark fibre pair (159.4 km, 36.7 dB) since May 2004. • One Side Amplification (OSA NIL approach): OA equipment in Prague only. No OA equipment in Plzen - lower service costs and higher availability (24/7 staff in Prague only) • Advantages: low cost, low size (1U), low power consumption, Linux, SNMP, reach up to 225 km, possibility of development, ….

CzechLight and PCLightEDFA 2in1 - PCLight equipment example • EDFA 2in1 reach at 1GE : • Booster up to 225km • Preamp up to 150km without filter • Preamp up to 225km with filter • Preliminary comparison of OA (EDFA) cost: • 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) Klub ředitelů
CzechLight and PCLightPCLight forthcoming • EDFA 2in1 works on 10 GE (tested in laboratory) • Long reach GE interface card (1550 nm) • Long reach GE interface card for bidirectional transmission on single fiber • PC Raman OA • etc. Klub ředitelů
