O &M of dark fibre networks ( based ) - good practices, procedures

1. O&M of dark fibrenetworks (based) - good practices, procedures Octavian Rusu RoEduNet

2. Agenda • IRU and DF IRU • NRENs and IRU • Options to get the DF • RoEduNet case • The deal • Costs • 6 year of operation

3. IRU • IRU - the exclusive and unrestricted (indefeasible – cannot be overturned) right to use the relevant capacity (including equipment, fibers or capacity) for any legal purpose • DF IRU - the exclusive and unrestricted (indefeasible – cannot be overturned) right to use a pair of fibre (from a cable) for any legal purpose • Period – at least 10 years

4. IRU for NRENs • Type of NREN: • governmental or non governmental • Funding • per year – not suitable for IRU • Multiannual – it depends… • Costs: • IRU - Per year or per period – see SEEFIRE or Porta Optica • Maintenance costs – difficult to be rightly estimated for long term period • Collocation costs – could be negotiated (usually same vendor), many times should be re-negotiated in the IRU period

5. Other options • There are other options instead of IRU • Building of the infrastructure • Not suitable for NRENs in most cases but could be suitable for public-private partnership • More suitable for the national/regional network, more difficult for last mile or access network • Partnership with national/regional operator • The solution adopted by RoEduNet

6. The Deal • Use any available fiber segment (one pair) from Telecomunicatii CFR (state owned company), install the DWDM equipment and provide in return: • at the time of installation the same number of lambdas for the NREN and for the partner • Reserve half of the DWDM channels for the partner • Cover maintenance costs for the optical equipment • Apart of the fiber pair we’ve got (provided by the partner): • Cable/fiber maintenance (max 8 hours repair time) • Hosting/collocation of the equipment • No commercial contract between the NREN and the partner – negotiations for more than 2 years (2003-2006) – not possible without political support!!

7. The Optical Network about 6000 km of fiber

8. The costs • Quite close to the calculations from SEEFIRE for equipment (5.6 MEuros incl. taxes) • 4300 km of fiber in 46 segments • 56 sites (ROADM: 18, ADM: 23, Amplifiers: 15) • 79 lambdas installed (10 Gbps Ethernet or SDH) • Operation and maintenance: • For the fiber – done by the partner according to the agreement • For the equipment – done by RoEduNet :: contract with Felix Telecom

9. Operation and Maintenance Romanian Education and Research Network - RoEduNet

10. Upgrades • The network has been extended: • From 4300 to 5600 km • From 56 sites to 69 • The national backbone upgraded to 100 Gbps (six lambdas, one for each main NOC)

11. Conclusions • Lessons learned • Discover the underused resources (DF), push for the contribution to the education of the nation • Make a good deal and, most important, a fair one for all partners • Try to understand the needs of the partner(s) and, if possible, don’t hesitate to help, sometime you will have the service returned • Do not compete with partners of with ISPs Thank you - Questions
