Main changes in REN design Traditional building elements (procured): data transmission services, routers, terminals, etc. Traditional network function: provide best effort IP connectivity New building elements: dark fibres, optical transmission equipment, switches New network function: provide E2E circuits Multi-vendor networking for feasibility (in multiple domain) and cost effectiveness (in single domain) – standards, MSA, etc. are needed. This is similar as on circuit and computer system design level. Prague May 25th, 2004 Procurement and lighting of dark fibre

Dark fibre deployment in RENs Increasing and world-wide deployment of dark fibre (acquisition of dark fibres instead of SDH or lambda services) – without moving back Lease of fibres: 0.4 – 0.5 Euro/m/pair/year, including maintenance Discounts on long term lease, disadvantages of IRU (prepayment, taxes and bankruptcy) Increasing number of customer premises connected by fibre: to achieve this is more difficult problem than intercity fibre procurement Building first mile fibre lines: about 30 Euro/m for 12 strand cable, 6 month in ground Prague May 25th, 2004 Procurement and lighting of dark fibre

CEF network architecture will be new Prefer network architecture with NIL (single span) lines and without overlaying (concurrent) fibres KIS rule for fibres: Keep It Short, including connections crossing state borders Realization of lambdas by own equipment and fibres for long distance data transmission Search actively for new fibre providers (railways, highways, power distribution companies, fuel distribution companies, gas distribution companies, cable TV companies, etc.) Search actively for regional authorities and local boards cooperation on laying first mile fibre cables Prague May 25th, 2004 Procurement and lighting of dark fibre

How to go from telco services to dark fibres Procure dark fibre before lambdas procurement Procure your first dark fibre line ASAP to acquire experience (to avoid staff fear of: maintenance, service, lighting fibre, management of in-line equipment, costs, manpower, etc.) Do not relay on one provider only, maintain concurrency (for price and for first mile acquiring) If price is not excellent, use annual contracts and re-procurement If dark fibre line is not offered but exists, use annual contract for lambda(s) and re-procure dark fibre Prefer remote management of in-line equipment with local assistance of service company (no „managed dark fibre service“ from ISP) Prague May 25th, 2004 Procurement and lighting of dark fibre

We need non-expensive fibre footprint KIS: Connect dark fibres used by NREN by a short cross-border fibre lines (called also Near over Border - NoB) Use WDM equipment on national and cross-border fibres for implementation of lambdas between GN2 PoPs/end users This KIS approach avoids double payment of fibres or lambdas (parallel lines are paid by NREN and DANTE), in the biggest item of budgets Such change of networking strategy is difficult, feasibility study and testbeds are needed Prague May 25th, 2004 Procurement and lighting of dark fibre

Let us introduce: 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: ??? (forthcoming) OA costs are the biggest item in long distance transmission systems costs (e.g. 60%) => PC Light helps to radically change WAN/MAN costs Prague May 25th, 2004 Procurement and lighting of dark fibre

EDFA 2in1: 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, low size (1U), low power consumption, Linux, SNMP, reach up to 225 km, possibility of development, ….
