Initiatives towards NG-PON
1. BIT-RATE INCREASE (XGPON, to 10G)
– IEEE 802.3av Task Force
• DS:1570nm, US: 1300nm
– FSAN XGPON 10G/2.5G
2. REACH EXTENSION– GPON new TX/RX classes: C (30dB), C+(32dB)
– ITU-G.984.6 Mid-span Extender (20 to 60 Km)
3. WDM (NUMBER OF CHANNELS / SERVICES): – ITU-G.984.5 – NG-PON-1 (coexistence, same fibre plant) – NG-PON-2

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

The CO sends WDM signals
to the Remote Nodes (RN)Each RN drops its assigned
channels ast thecorresponding wavelengthby 2 filters and a 50/50 forresilience that splits thesignals to 2 TDM trees
Signals are amplified byEDFs The Remote Nodes receive
the pumping power for theEDFs from the WDM ring
Once amplified, the signalsare transmitted to the ONUsUpstream signal path is

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

– This makes it more challenging and exciting
• We continue to improve the robustness as we gofrom Lannion to FTTH Council in Milan
– Next week testing continues

Field trial tests
SARDANA network transmission over 55 Km, over the deployedLannion 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 multimediaservices.

Final Outcomes
• SARDANA project targets the ultimate extension of the limitsof FTTH Passive Optical Networks, as a practical transparentapproach 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 broadbandservices (20-1-2011)
– Public Demo at FTTH Council Conference, Milan (9/10-Feb-2011)• FTTH SHOWROOM (YELLOW-2)
• Network/system/subsystem/component design guidelines andprototypes 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

Things for continuing R&D
• FEC has not been implmented and would be convenient.
• Connectors are critical (return loss near ONU, high-power at ring)
• RSOA technology has to evolve, for higher GAINxBW, (and injected power) from:
– 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)
• A secondary pump source is convenient to reach 100 Km
– Or from ASE from SOAs, as has been demonstrated.
• Rayleigh back-scatering is critical for distribution > 3Km.
– 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
