  1. Broadband Fiber Access Network Solution - Passive Optical Network (PON) - NEC Corporation

  2. FTTx is happening NOW! • Fiber deployment in access network is more rapid than expected • Over 10% broadband installations are FTTx (Source: DSL Forum) • Fiber-to-the-home networks will reach more than 85 million homes by 2011, representing 5% of all households, Heavy Reading forecasts • Cable Operators considering FTTH/FTTB for Greenfield deployments • Facing strong competition – Telcos are now offering or plan to offer multi-play services over fiber • Higher bandwidth demand continue to drive the innovation in cable industry • DOCSIS 3.0 migration slower than expected • Fiber is perceived as the ultimate access pipe to home • Asia Pacific is leading the way in FTTH deployments • Japan and Korea are main drivers; China will catch-up • Number of Asian FTTH users will grow eightfold in the next five years, from five million in 2005 to more than 40 million in 2010 (Source: TDG) • NTT expects to have 30 million subscribers by end of 2010 • Next generation broadband networks in US and Europe are FTTx based • FTTH: Verizon, France Telecom • FTTN: AT&T, Telecom Italia, DT

  3. FTTx Options Splitter/ Active Switch Fiber FTTH GEPON/GPON/Ethernet IP Network Includes fiber to both individual houses and to apartment blocks (aka FTTH) Splitter/ Active Switch Ethernet ONU GEPON/GPON/Ethernet Fiber FTTB IP Network To an office/apartment block IPDSLAM FTTN IP Network GEPON/GPON/Ethernet ADSL2+/VDSL2 Up to about 1,500 meters from the premises Cabinet FTTC GEPON/GPON/Ethernet IP Network ADSL2+/VDSL2 Up to about 150 meters from the premises (aka FTTCab)

  4. FTTx Growth in Japan Mainly GEPON FTTx overtook DSL

  5. Revenue of DoCoMo Time to market NTT is seeing revenue for mobile service is saturated.It is expected to grow Broadband market of FTTH in particular. It is recommended to start FTTH service from now even by small start, but by doing this keep know-how and experience for mass adaptation.

  6. FTTx Market Drivers • New revenue source for Fixed Operators • Triple play service • World wide deployment • Ability to leverage existing infrastructure • Governmental policy to drive Broadband

  12. PON Technology Comparison GE-PON is the best suited technology for Ethernet service delivery.  Eliminates unnecessary loss due to fragmentation of Ethernet frame, overhead bytes and complicated encapsulation  Simplified layer structure for simplified management  Bandwidth expansion to Gigabit Ethernet EFM : Ethernet in the First Mile GEM : G-PON Encapsulation Method

  13. PON or EPON • IEEE-based GEPON (E-PON) • IEEE 802.3ah • GE-PON 1310/1490nm • Ethernet-based 1Gbps, Specific to Ethernet service . • ITU-T-Based GPON • ITU-T G.984 • G-PON 1310/1490 nm • Generic Frame with 2.4Gbps / 1.2Gbps • Full services (Ethernet, T1/E1, DS3/E3, ATM, ISDN) • ATM and Ethernet frames are encapsulated into generic frame • Since Ethernet / legacy-dedicated line can be accommodated, American and European regions are supposed to deploy G-PON based FTTH.

  14. G-PON vs GE-PON:Why GE-PON? GE-PON: “Widely deployed” • Key Benefits • Low Risk • Low CAPEX and OPEX • Built for Ethernet Infrastructure • Multi-point variant of Ethernet Technology WHY? Simplicity Proven Technology Cost Advantage “GE-PON is still the dominant [FTTH] technology, and this trend will not change in the next two years,” Dittberner said Source:

  15. G-PON vs GE-PON:Why G-PON? G-PON: “ITU-T Standardized Higher Service rate” • Key Benefits • Higher down stream (2G for 64split) • More suitable for IPTV • E1 accommodation by native WHY? 2G Down stream Interoperability ATM/Ether/TDM Accommodation

  16. G-PON vs GE-PON:Technologies and Targeted Applications

  17. G-PON vs GE-PON : NEC Standing position • Depend on the Carrier’s policy • Filed experience by GE-PON in Japan • ATM Base IP DSALM/MSAN enhancement to support G-PON • Participating Standardization activity both ITU-T and IEEE. • Recognize both technology has Pros and Cons GE-PON : Fast Deployment, Matured technology, Lower cost G-PON : TDM Accommodation, migration from ADSL/MSAN to FTTx
