CESNET l CESNET 2 network Dark fibre experimental facility (EF) l 5 112 km leased fibres (high coverage on 78 864 km 2 ) l – Including 995 km of single fibre lines – Including Experimental facility 535 km of dark fibre CEF Networks Workshop 2009 3

Motivation for lit fibre service 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 l CEF Networks Workshop 2009 4

Used procedure – what we learned l l Detailed description of procuring of lit fibres is on http: //www. ces. net/events/cef 2007/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 CEF Networks Workshop 2009 5

Ways of lit fibres service acquiring l l l 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) CEF Networks Workshop 2009 6

Previous situation in 2007 CEF Networks Workshop 2009 7

Steps of history l l l First CL (Czech. Light) deployment in the year 2004, specifically CLA PB 01 (Czech. Light Amplifier 2 in 1, Booster and Preamplifier) was on Praha – Plzeň line with length of 159 km in Czech. Light EF and on Praha – Hradec Králové, length of 150 km in CESNET 2 network. Since March 2005 CLA DI 01 (Czech. Light Amplifier Dual. Inline)has been successfully working on Czech. Light EF line Praha-Brno, 284 km, as one and only inline amplifier. At the beginning of 2006 CLA PB 01 was equipped on the first Cross Border Fibre (CBF) line Brno – Bratislava, 182 km. In the middle of 2006 CBF Brno – Vienna, 224 km was deployed by a new prototype CLA PB 02. CEF Networks Workshop 2009 8

New optical transmission DWDM systems, based on own open photonic devices called the Czech. Light (CL) family Main types without gain flattening for up to 8 channels: l CLA PB 01 Low noise preamplifier and booster amplifier with output power up to 20 d. Bm and optional ALS (Automatic Laser Shutdown) l CLA PB 02 Low noise preamplifier and high-power booster amplifier with output power up to 27 d. Bm and built-in ALS l CLA DI 01 Dual in-line amplifier with output powers up to 15 d. Bm Main types with gain flattening for up to 32 channels: l CLA PB 01 F Gain flattened low noise preamplifier and booster amplifier with output power up to 20 d. Bm and optional ALS l CLA PB 02 F Gain flattened low noise preamplifier and high-power booster amplifier with output power up to 27 d. Bm and built-in ALS l CLA DI 01 F Gain flattened dual in-line amplifier with output powers up to 15 d. Bm CEF Networks Workshop 2009 9
