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

Octavian Rusu RoEduNet

SLIDE 2

Agenda

 IRU and DF IRU  NRENs and IRU  Options to get the DF  RoEduNet case  The deal  Costs  6 year of operation

SLIDE 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

SLIDE 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

SLIDE 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

SLIDE 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!!

The Optical Network

about 6000 km of fiber

SLIDE 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

Operation and Maintenance

Romanian Education and Research Network - RoEduNet 9

SLIDE 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)

SLIDE 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

ne 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
