CESNET

CESNET2 network Dark fibre experimental facility (EF)

5 112 km leased fibres (high coverage on 78 864 km2 )– Including 995 km of single fibre lines

– Including Experimental facility 535 km of dark fibre

4CEF Networks Workshop 2009

Motivation for lit fibre service

Full fibre capacity can be dedicated for NREN! (no return to traditional telco services)

NREN can share leased dark fibre with other organizations (legal bodies) Lighting is outsourced (Some NRENs has no staff experienced in optics

and electronics) Buying of service instead of investment into equipment (OPEX instead of

CAPEX) Costs of adding lambdas (or other extensions) should be part of contract Provider will obtain experience with new type of service and can offer

this new type of service to other customers Deployment of new photonics devices – technology transfer to telco

providers

5CEF Networks Workshop 2009

Used procedure – what we learned

Detailed description of procuring of lit fibres is on http://www.ces.net/events/cef2007/p/altmannova.ppt

Project of lighting can be prepared by NREN staff or by independent company Contract with one provider per whole line Detailed description of acceptance agreement (part of handover report)

- Description of the line (address, contact persons, length, attenuation…)- Channel plan- Block diagram of the line (equipment, points of power measurement)- Tables and charts of measurement- Setting of equipment- Result and conclusion

6CEF Networks Workshop 2009

Ways of lit fibres service acquiring

Upgrade of leased dark fibre lines (the most applied solution) – extensive experience

Tender for lit fibre HW order and deployment by own staff (verification of

new methods)

Steps of history

First CL (CzechLight) deployment in the year 2004, specifically CLA PB01 (CzechLight Amplifier 2in1, Booster and Preamplifier) was on Praha – Plzeň line with length of 159km in CzechLight EF and on Praha – Hradec Králové, length of 150km in CESNET2 network.

Since March 2005 CLA DI01 (CzechLight Amplifier DualInline)has been successfully working on CzechLight EF line Praha-Brno, 284km, as one and only inline amplifier.

At the beginning of 2006 CLA PB01 was equipped on the first Cross Border Fibre (CBF) line Brno – Bratislava, 182km. In the middle of 2006 CBF Brno – Vienna, 224km was deployed by a new prototype CLA PB02.

9CEF Networks Workshop 2009

New optical transmission DWDM systems, based on own open photonic devices called the CzechLight (CL) family

Main types without gain flattening for up to 8 channels: CLA PB01 Low noise preamplifier and booster amplifier with output power

up to 20dBm and optional ALS (Automatic Laser Shutdown) CLA PB02 Low noise preamplifier and high-power booster amplifier with

output power up to 27dBm and built-in ALS CLA DI01 Dual in-line amplifier with output powers up to 15dBmMain types with gain flattening for up to 32 channels: CLA PB01F Gain flattened low noise preamplifier and booster amplifier with

output power up to 20dBm and optional ALS CLA PB02F Gain flattened low noise preamplifier and high-power booster

amplifier with output power up to 27dBm and built-in ALS CLA DI01F Gain flattened dual in-line amplifier with output powers up to 15

RESULTS Enough time for project preparing and negotiation is

necessary

After implementation and testing, 15 upgraded lines of CESNET2 are running with very high reliability

Projects are successful and can be repeated
