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

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

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,…)
