2 CEF Networks Workshop 2009 Author participates on Optical networks activity of CESNET research program, GN3 and Phosphorus project Presented ideas do not necessarily reflect an official opinion of the GN3, CESNET or any other institution or project.

3 CEF Networks Workshop 2009 CESNET l CESNET2 network l Dark fibre experimental facility (EF) l km leased fibres (high coverage on km2 ) –Including 995 km of single fibre lines –Including Experimental facility 535 km of dark fibre

4 CEF Networks Workshop 2009 Motivation for lit fibre service l Full fibre capacity can be dedicated for NREN! (no return to traditional telco services) l NREN can share leased dark fibre with other organizations (legal bodies) l Lighting is outsourced (Some NRENs has no staff experienced in optics and electronics) l Buying of service instead of investment into equipment (OPEX instead of CAPEX) l Costs of adding lambdas (or other extensions) should be part of contract l Provider will obtain experience with new type of service and can offer this new type of service to other customers l Deployment of new photonics devices – technology transfer to telco providers

5 CEF Networks Workshop 2009 Used procedure – what we learned l Detailed description of procuring of lit fibres is on l Project of lighting can be prepared by NREN staff or by independent company l Contract with one provider per whole line l 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

6 CEF Networks Workshop 2009 Ways of lit fibres service acquiring l Upgrade of leased dark fibre lines (the most applied solution) – extensive experience l Tender for lit fibre l HW order and deployment by own staff (verification of new methods)

7 CEF Networks Workshop 2009 Previous situation in 2007

8 CEF Networks Workshop 2009 Steps of history l 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. l 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. l 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.

9 CEF 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: l CLA PB01 Low noise preamplifier and booster amplifier with output power up to 20dBm and optional ALS (Automatic Laser Shutdown) l CLA PB02 Low noise preamplifier and high-power booster amplifier with output power up to 27dBm and built-in ALS l CLA DI01 Dual in-line amplifier with output powers up to 15dBm Main types with gain flattening for up to 32 channels: l CLA PB01F Gain flattened low noise preamplifier and booster amplifier with output power up to 20dBm and optional ALS l CLA PB02F Gain flattened low noise preamplifier and high-power booster amplifier with output power up to 27dBm and built-in ALS l CLA DI01F Gain flattened dual in-line amplifier with output powers up to 15 dBm
