Approach and basic modules
• WDM ring: Resilience
• (up to 1.2Tbit/s)
• TDM trees
• Passive Remote Nodes (RN):– Cascadable Add&Drop
– 2-to-1 fibre interface
– Remotely pumped (from CO) optical amplification by EDFs
– Athermal splitters and fixed filters
• CO (OLT):– Centralizes the light generation and control
– Stack of lasers serving TDM trees
– Standard G/E-PON equipment adapted to SARDANA
• Simple colourless ONU:– Reflective
– Single fibre & wavelength

CO
RNn RN1
The CO sends WDM signals to the Remote Nodes (RN) Each RN drops its
assigned channels ast the corresponding wavelength by 2 filters and a 50/50 for resilience that splits the signals to 2 TDM trees Signals are amplified by
EDFs The Remote Nodes
receive the pumping power for the EDFs from the WDM ring
Once amplified, the signals are transmitted to the ONUsUpstream signal path is
marked with static figures

Wavelength allocation• In SARDANA there is a significant dependency of:
– the power budget
– on the wavelength allocation of US/DS channels
– on the pump generation for remote amplification.
• SARDANA wavelength allocation plan– possible compatibility with XGPON1
– not with video overlay

• CAPEX – Analysis of:
• PASSIVE:
– Fibre infrastructure
– Remote Node
• ACTIVE:
– ONU
– OLT
– Pump
– Monitoring and protection
– Active equipment price estimation and learning curve
– CAPEX (overall for SARDANA & GPON): Cost/user vs. density
• SARDANA is cost effective in a wider range of user densities.

SARDANA GREEN TOUCH
• Deep analisys has been performed in order to compare the SARDANA approach with the main access technologies.
• In principle two SARDANA situations have been considered: SARDANA1 and SARDANA2. First one is SARDANA with “non commercial” devices. Second is SARDANA with market ready components.
• In figure are reported the results for unlimited and limited upstream. SARDANA, especially the version 2, express the best performances in terms of power efficiency.

• Services over SARDANA were successfully demonstrated
• Experience from the demo was used to improve the system performance
– MAC operation Upstream and Ranging
– Burst transmitter optics
– Protection and monitoring system
• System was shipped to Lannion in early December– Reintegration took place December to January

2) The OLT RX1-2 connect US to either East or West DWDM DEMUX
When the protection and monitoring system is used the connections go via it.
3) There is a pre-amplifier (PA) upstream for all wavelengths before the DWDM DEMUX.
There is also a boost amplifier (BA) downstream for all wavelengths after the DWDM MUX.
4) DS and US fiber spools (5-25km) run between the OLT and the RN1-2

From Espoo to Lannion
• The demo system in Espoo had all the equipment co-located
• Lannion trial has distributed equipment on several sites
– This makes it more challenging and exciting
• We continue to improve the robustness as we go from Lannion to FTTH Council in Milan
– Next week testing continues

SARDANA Field-Trial (Lannion, 20th January 2010)
The Orange Labs facilities are connected to a 18 Km "open" fiber network.
This fiber network is located along the Bretagne Lannion area, and managed by the cluster Media&Network.
12-fibre ring cable plus distribution trees.
Reintegration of SARDANA systems took place December to January

Service Delivery with fs|cdc
SARDANA showcase, Milan, February 2011, FTTH Council Europe 201143 [email protected]
Field trial tests
SARDANA network transmission over 55 Km, over the deployed Lannion area cable infrastructure plus extra local spools.
Optical connections between ImaginLab, ENSSAT and OrangeLab.
Different communications services transmitted through:
2x Bidirectional 1G Ethernet using RSOA and SFPs.
10G / 2.5 XGPON scrambled burst data.
Bidirectional 10G Ethernet using tuneable laser ONU.
Functionality shown:
Channel protection (fibre cuts).
ONU colourlessness.
Multi-operability.
High bandwidth real time bidirectional HD multimedia services.

Final Outcomes
• SARDANA project targets the ultimate extension of the limitsof FTTH Passive Optical Networks, as a practical transparent approach to access&metro convergence.– Sardana Test-Bed Demonstration in Espoo-Finland (28-Oct-2010)– Sardana Field-Trial in 12-2010 in Lannion-France, with new broadband
services (20-1-2011)– Public Demo at FTTH Council Conference, Milan (9/10-Feb-2011)
• FTTH SHOWROOM (YELLOW-2)
• Network/system/subsystem/component design guidelines and prototypes for NGPON2.
• Contribution to:– Regulatory Bodies on Broadband Access to citizens (multi-operator
infrastructure sharing strategy, etc). – International Standards on next-generation FTTH like NGPON2.

Things for continuing R&D
• RSOA technology has to evolve, for higher GAINxBW, (and injected power) from current:
– 14 dB 1.2 GHz (TO-CAN), equalized for 2.5Gbit/s
– 18 dB 0.8 GHz (TO-CAN)
– 10 dB 3 GHz (Butterfly )
– -10 dB 10 GHz (REAM)
– 5 dB 10 GHz (SOAREAM chip)
• FEC has not been implemented and would be convenient.
• Connectors are critical (return loss near ONU, high-power at ring)
• A secondary pump source is convenient to reach 100 Km– Or from ASE from SOAs, as has been demonstrated.
• Rayleigh back-scattering is critical for distribution > 6Km. – Increase ring, decrease drop, 2 fiber-feeder.
– Also can be reduced with several techniques developed.
• Many ideas have come up along the 3 years for future improvement.
• 1-2 year for Development.
• _x_? for Deployment
