CzechLight – research into practical live

Effort to transform results of network research to support CzechLightDeployment of WDM/DWDM NIL 1 GE and 10 GE transmissionsDeployment of results of PCLight Potential utilization of results of the Liberouter project – www.liberouter.org (1 GE and 10 GE interface cards, repeaters, transponders,…)

NIL 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 2 x 10 GE

290 km 10 G DWDM

Lets connect by cost effective way who needs itRacked PC = fast development + good reliabilityDesign kit for wide area fibre networks, based on racked PCsStart with OA - OA cost is biggest item in long distance transmission systems cost (e.g. 60%)

EDFA 2in1 - PCLight equipment example

PC with build-in OA EDFA booster and preampSuccessfully 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, ….

EDFA 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)
