8. 8 CEF Networks Workshop 2010 Photonic transmission layer in CESNET2 ● Multivendor solution allows transition of photonic lambdas thru PoPs  Cisco DWDM - ONS 15454 MSTP  Open DWDM - based on own open photonic devices called the CzechLight (CL) family and developed by CESNET ● Links for detailed information:  http://www.cesnet.cz/doc/2009/zprava/nren.html  http://www.cesnet.cz/doc/2010/networking-studies/

9. 9 CEF Networks Workshop 2010 Transmission systems in CESNET2 ● Combination of equipment developed for commercial internet services and flexible solution tailored to special needs of R&E network (including economy needs) ● Cisco DWDM system  8 lines n x 10G  1 410 km ● Open DWDM system  20 lines (5 lines n x 1G plus 15 lines n x 10G)  2 660 km

12. 12 CEF Networks Workshop 2010 CL deployment history ● First CL 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 has been successfully working on CzechLight EF line Praha-Brno, 284km, as one and only in-line 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, 221 km, was deployed by a new prototype CLA PB02.

13. 13 CEF Networks Workshop 2010 Open DWDM deployment up to September 2010 CESNET2 and CBFs Number of CLA Length (km) 20 lines include as well:392 660 8 single fibre lines16905 3 fibre pair of CBF6521 CESNET EF Number of CL devices Length (km) 3 lines 8 x CLA + 2 x CL VMUX760

14. 14 CEF Networks Workshop 2010 Lit service on single fibre ● Open DWDM advantage : can be used on single fibre lines ● Price of single fibre leasing is about 60% of pair of fibres price ● Lighting of single fibre is cost effective. We use it to achieve dual access to some PoPs of CESNET2 under available budget

15. 15 CEF Networks Workshop 2010 Lit fibre service ● Newly developed types of CL equipments or lit services are tested on Experimental Facility ● Tested services developed by CESNET can be ordered as service ● Our providers of dark fibre and lit fibres services  ČD-Telematika, a.s.  České radiokomunikace, a.s.  GTS Novera s.r.o.  Tűrk Telecom (Invitel International CZ s.r.o.)  Sloane Park Property Trust a.s. ● Providers have acquired experience with new type of service based on Open DWDM photonic system developed and licensed by CESNET and can offer this new type of service to other customers ● CESNET licences for CL family equipment obtained by Optokon Co., Ltd, spol. s r.o. and RLC Praha a.s. ● CESNET licences are available for other companies

17. 17 CEF Networks Workshop 2010 Transition of photonic lambdas between Cisco DWDM and CL DWDM ● Implementation of accurate time signal transfer demonstrates the capabilities of photonic networks  Photonic transmission took place on operational lines during Czech-Austrian experiment on March 1 and 2 which compared the time scales of atomic clocks  Transition from Cisco DWDM to CL DWDM was realised in Brno Praha CESNET2 Brno CESNET2 Vienna ACOnet 298km 221km
