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 ATT, Telecom Italia, DT

FTTx Growth in Japan
Mainly GEPON
FTTx overtook DSL
5
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.

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

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.

G-PON vs GE-PONWhy GE-PON?
GE-PON Widely deployed
WHY?
Simplicity
Proven Technology
Cost Advantage

• Key Benefits
• Low Risk
• Low CAPEX and OPEX
• Built for Ethernet Infrastructure
• Multi-point variant of Ethernet Technology

GE-PON is still the dominant FTTH technology,
and this trend will not change in the next two
years, Dittberner said

G-PON vs GE-PONWhy G-PON?
G-PON ITU-T Standardized Higher Service rate
WHY?
2G Down stream
Interoperability
ATM/Ether/TDM Accommodation

• Key Benefits
• Higher down stream (2G for 64split)
• More suitable for IPTV
• E1 accommodation by native

G-PON vs GE-PON Technologies and Targeted
Applications
Major Carriers Applications Key Criteria
GE-PON - NTT, SBB, KDDI Japan Korea Telecom - FTTH and FTTB (Triple play Service) - Available, cheaper, and matured technology
G-PON - Verizon, US - FT, TI, BT and other EMEA tier-1s - FTTH (sub-urban areas) - FTTB (MDU/MTU) - FTT Business (Legacy TDM Services) - Long-term investment in standards (ITU-T) - Native TDM support - Up to 2.5 Gbps downlink
Both G-PON and GE-PON - CHT, Taiwan - BSNL, India - CTC/CNC, China - FTTH Residential (use GE-PON) - Legacy Migration (G-PON) - FTTB (GE-PON/G-PON) - Deploy the available technology (GE-PON) - Deploy G-PON for legacy services
17
G-PON vs GE-PON NEC Standing position

• Depend on the Carriers 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
