Optical Fiber Project

1. Optical Fiber Project CEF Networks workshop 2005 – lorga@fccn.pt

2. Index • Framing • Goals • Procedures • Fiber cable • Local Loops • Transmission • Routing • Management • Services • Future Work CEF Networks workshop 2005 – lorga@fccn.pt

3. Framing • Investment vs. Maintenance • Inadequate corporate solutions in the national market • Geographical distribution • Insufficient growth when compared with other NREN. • Availability of a fiber provider CEF Networks workshop 2005 – lorga@fccn.pt

4. Goals – A new approach! • New infrastructure for the long run • Gain more autonomy towards the market • Solve the “long lasting”capacity limitations • Be side by side with the most advanced NREN • Provide the means for high bandwidth projects and services CEF Networks workshop 2005 – lorga@fccn.pt

5. Goals – Guidelines • New and simpler network design • Ethernet based • 10GE backbone • Nx1GE access • Same Control panel for IPv4/IPv6 • Redundancy in the backbone through a provider • New backbone for the whole network • Stage I – connecting Lisbon-Braga CEF Networks workshop 2005 – lorga@fccn.pt

6. Procedures • Passive fiber network • FO for the long distances • Local loops using fiber • Equipment • Transmission (Ethernet). • Routing (IP). CEF Networks workshop 2005 – lorga@fccn.pt

7. Procedures • International tender for long distance cable • Winner - Refer Telecom (Railway Operator) • Each local loop with a different approach • Always trying to use existing pipes CEF Networks workshop 2005 – lorga@fccn.pt

8. Procedures - Transmission • Limited to a public announcement • Several proposals received • Second round with best proposals • Best-and-Final-Offers were asked • ADVA was chosen CEF Networks workshop 2005 – lorga@fccn.pt

9. Procedures - Routing • Similar to the transmission, without a public announcement • Several proposals received • Second round with best proposals • Best-and-Final-Offers were asked • Cisco was chosen CEF Networks workshop 2005 – lorga@fccn.pt

10. Long Distance cable – Features 48 Optical fibers from witch: • 24 x ITU-T G.652C (without water peak) • 24 x ITU-T G.655 CEF Networks workshop 2005 – lorga@fccn.pt

11. Long Distance Cable – Tests made Tested: • Spectral attenuation • Chromatic dispersion • Polarization Modal Dispersion • Reflectometry attenuation • Insertion loss CEF Networks workshop 2005 – lorga@fccn.pt

12. Long Distance Cable – Features • Dialectical central strength member: fiberglass • 5 loose tubes – 4 with 12 fibers each • Water resistant • Anti-rodent armouring • Complies with crushing, tension and temperatures specifications CEF Networks workshop 2005 – lorga@fccn.pt

13. Cable - curiosities • Mean attenuation of 0.21dB/Km • Can connect 150Kms with with nothing-in-line CEF Networks workshop 2005 – lorga@fccn.pt

14. Access Local Loops Strategy: • use existing pipes • establish partnerships with pipe owners • always have a ring topology Developing: • Aveiro, Braga, Coimbra, Lisbon and Porto; CEF Networks workshop 2005 – lorga@fccn.pt

15. Access Local Loops - Aveiro CEF Networks workshop 2005 – lorga@fccn.pt

16. Access Local Loops – Lisboa CEF Networks workshop 2005 – lorga@fccn.pt

17. Access Local Loops - Difficulties • To coordinate all involved entities to meetings and surveys. • Unexpected events on-site CEF Networks workshop 2005 – lorga@fccn.pt

18. Transmission Solution • Minimalist approach - several distinct point-to-point solutions; • Intelligence and services on the IP level • The transmission is just the 10GE and 2GE access links • Solution -> ADVA Optical CEF Networks workshop 2005 – lorga@fccn.pt

19. Routing Equipment Cisco Equipment • 1 router in Lisbon • 1 router in Porto • 1 router backup/test router • 10G Lan-Phy XENPAK ports • 1G SFP ports CEF Networks workshop 2005 – lorga@fccn.pt

20. FCCN -Lisboa FCCN-Porto U. Coimbra / IPC U. Aveiro U. Minho U. Lisboa U. Tec. Lisboa U. Nova Lisboa Routing – Topology • Dual star topology (Lisbon and Porto) • Network “intelligence” on the IP level • No more core/edge design for the fiber connections (economical reasons) • Fully redundant equipment • Lisbon-Porto backup link from a commercial provider CEF Networks workshop 2005 – lorga@fccn.pt

21. Management and operation – TNMS CORE TNMS-CORE from Siemens: • Integrated management • Centralized monitoring and configuration • End-to-end connection management • Alarm and error monitoring • Performance management CEF Networks workshop 2005 – lorga@fccn.pt

22. Management and Operation – Approach • Monitoring using another fiber pair with passive transceivers • Ethernet switches directly connected to the transmission equipment • Non usage of dedicated cards/equipment CEF Networks workshop 2005 – lorga@fccn.pt

23. IP Services • Migration of current IP services to the new backbone: • IPv4/IPv6 Unicast and Multicast • R&D e .COM Classes of Service • Offer new and richer classes of service • Study the possibility of having VPNs CEF Networks workshop 2005 – lorga@fccn.pt

24. Other Connections – Phase II • Consulting market again in 2005. • New advanced solutions of renting fiber, lambdas, GE and FE • Redundancy solution for the backbone, through a national ring CEF Networks workshop 2005 – lorga@fccn.pt
