Research Department APM Meeting Prague February 24th, 2005CzechLight Testbed 9 CzechLight configuration l Core node in Prague CISCO with 10 G DWDM SONET, 4xGE CISCO C3550 – 12G CISCO C6503 with 10 GE and GE l Core node in Brno CISCO with 10 G DWDM SONET, 4xGE

Research Department APM Meeting Prague February 24th, 2005CzechLight Testbed 10 PC Light l Design Kit for wide area fibre networks, based on racked PCs with build-in optical amplifier modules l Multi-vendor (multi-source) building elements l Preliminary comparison of OA (EDFA) costs: –OA from „ISP vendor“: USD –OA from „optical vendor“: USD –OA from „module vendor“: 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

Research Department APM Meeting Prague February 24th, 2005CzechLight Testbed 11 EDFA 2in1 v2.0: PC Light equipment example l PC with build-in OA EDFA booster and preamp l 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 l 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) l 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,…)
