  6. NGPON2 Standard Progress

  7. FSAN Introduction • The Full Service Access Network (FSAN) Group is an interest group for services providers and vendors to specify applicable standards. • FSAN was started in 1995 • FSAN has over 80 member companies representing the implementers, manufacturers, and test houses for PON Systems. • FSAN’s significant works • GPON IOP • XGPON1 requirements and standards • XGPON1 IOP • NGPON2 requirements

  8. Relationship between FSAN and ITU White Paper Contribution

  9. NGPON2 Motivation

  10. Drive for NGPON2 • Service drivers • Growing bandwidth demand Video evolution, video conference, Digital Home, Social networking, Cloud Services, Gaming, P2P traffic • End user requirements • Backhauling • Network drivers • PON upgrade path • Simplification of operational processes • Node consolidation • Power reduction • Openness

  11. PON Technology Migration Downstream 100G Upstream Migration according to requirement,ODN coexistence , open Big split ratio，High bandwidth，Long reach，Power saving TWDM-PON + PtP WDM 40G Future Coherent/ OFDM 10G 10GEPON XGPON1 2G GPON 1G GEPON 0.6G A/BPON TDM-Based PON NG-PON2 0.15G Year 1998 2004 2010 ????

  12. NGPON2 Choices Coexistence Enables gradual migration from pre-existing PON systems over the same ODM OLT&ONU replacement Enables migration over a legacy ODN by a “complete” replacement of preexisting PON terminals Modified ODN Something other than only power splitter ODM FDM PON OFDM PON WDM PON WDM-TDM PON WDM PON(colorless)-PS-ODN WDM PON(colored)-PS-ODN WS-TDM PON WDM PON(colorless)-WS-ODN WDM PON(colored)-WS-ODN Coexistence OLT&ONU Replacement Modified ODN XGPON1 (US 2.5G;DS 10G) NGPON2 >=40GDS Aggregated capability per feeder ONU Substainable GPON Year 2006 ~2010 ~2015

  13. NGPON2 Technology

  14. TWDM-PON • TWDM-PON has been confirmed to be the main technology of NGPON2. • Time and wavelength division multiplexed PON • 4 XGPON1 carried on 4 wavelength. • 40G PON: 40G downstream; 10G upstream • Coexistence • Current GPON and XGPON1 can have no change • Can coexist with GPON and XGPON1 • Key technology • Tunnable receiver • Tunnable filter

  15. TWDM-PON Architecture • TWDM-PON reuses XG-PON technologies • Downstream multiplexing Upstream access techniques Timeslot granularity • Multicast capability • Bandwidth allocation mechanism. • OLT multiplexes and demultiplexes multiple wavelengths.

  16. TWDM-PON Wavelength Plan1

  17. TWDM-PON Wavelength Plan2

  18. TWDM-PON Wavelength Plan3(Selected)

  19. TWDM-PON Coexistence and Migaration

  20. NGPON Standard G.989 G.989.1 - service G.989.2 - PMD PMD specifications (based on G.987.2, with changes) Including PHY parameters and requirements Architecture: • Backward compatible with G-PON, XGPON1, with higher data rate New concerns / Features • Security model and Proposal • Time Sync ITU-T Q2/SG15 G.989.3 - XGTC G.988 – G.OMCI Extensions to G-PON TC layer Adaptation to new PHY requirements May be subject to changes after its first version is published if necessary Extensions to G-PON, XG-PON OMCI layer Will require extensive work to make sure that nothing is broken and that references are properly handled in all documents 19

  21. WDM-PON • Each ONU is served by one or more dedicated wavelengths. • A number of OLT Tx/Rx components map PON client signals onto separate wavelengths, which are multiplexed onto a shared, bidirectional fiber • Two kinds of WDM PON • Point to point WDM PON • hybrid WDM PON : a wavelength (especially upstream) may be shared by two or more ONUs • A wavelength control block (λ control) may be present to control the transmitted and received wavelengths and the respectively connected ONUs.

  22. WDM-PON Architecture • Advantage • High bandwidth • No DBA algorithm requirement • Disadvantage • Expensive and very high power consumption • Wavelength allocation • Key Technology • Colorless ONU • IL FP • RSOA • Tunnable transmitter

  23. OFDM PON • Orthogonal Frequency Division Multiplexed (OFDM)-PON • Reliant on electronic digital signal processing (DSP) • Compensate physical-layer impairments • bandwidth flexibility.

  24. XLG-PON • Forty gigabit time division multiplexed PON (XLG-PON) • Increase the downstream speed of a TDM PON from 10 Gb/s (XG-PON, ITU-T G.987) to 40 Gb/s (XLG-PON) • Key Issues • Optical budget • APD bandwidth • Chromatic dispersion (CD) • Electronic complexity at higher speed:

  25. Coexistence of XLG-PON

  26. Other PON Technology • UDWDM-PON • SS WDM-PON

  27. Market Trend of Cortina

  28. Market Trend of Cortina • T4 MKT status • We have win most of tier 1 vendors and will win more tier 2 vendors • We will focus on 10G ONU design win the next half of this year • T5 Development • - we continue to build XGPON IP  • - continue to define and refine T5 as a product  • - engaging key customers for T5 (H Z Juniper ALU Mitsubishi) • - we will wait until the right timing to launch product 

  29. Summary

  30. Summary • FSAN has decided the TDWDM-PON is chosen to be the main NGPON2 technology. • P2P WDM-PON will be used in little scenario. • G.989 is started to be drafted in ITU • The real application of NGPON2 will be after 2015 • 10GEPON and XGPON1 will be used as migration to the next generation PON, but they will last for long time.
