Obstacles in Realizing FTTH IFC highly depends on Accommodation Ratio : Barrier for service area expansion Strengthen cooperation between plant deployment & sales FTTH Service Charge is High? No Killer Application at present Competitive environment solves Chicken & Egg Problem Difficulties in Prompt Provisioning NE Allocation Takes Long Time First Mile Bottleneck
ADSL vs. FTTH 1$=117JPY Fixed Monthly Charge Initial Charge $60 $200 179.50 $50 45.73 46.15 $150 $40 128.20 $30 27.78 $100 $20 $10 $0 with POTS w/o POTS ADSL (12M) FTTH $50 $0 Engineer Install 25.65 Customer Install ADSL (12M) FTTH
Obstacles in Realizing FTTH IFC highly depends on Accommodation Ratio : Barrier for service area expansion Strengthen cooperation between plant deployment & sales FTTH Service Charge is High? No Killer Application at present Competitive environment solves Chicken & Egg Problem Difficulties in Prompt Provisioning NE Allocation Takes Several Days First Mile Bottleneck
First Mile Bottleneck Newly Built House & Apartment No Bottleneck Existing Detached House In-house Wiring How to lead in fiber cable Existing Apartment Require consents from residents to use a equipment room and pipes
R&D to Overcome Obstacles OSS for Prompt Service Provisioning Network Element Allocation System Solutions for First Mile Finer & Flexible Fiber Cord Improved Wiring Method Improved Splicing Technologies FWA System Future Issues : DIY Ownership of ONU : Carrier to Customer Easy-to-handle optical cord & connector
Wireless IP Access System (FTTC) Objective : Prompt Provision of B-FLET s without Wiring in Rural Area Office Optical fiber cables AP Frequency band : 26GHz Baseband speed : 80Mbit/ Transmission distance 500 700 Number of WTs : 200 WT

Single Play? Video Provisioning Alternatives IP Video Possible degradation of Video Quality Copyright : Solutions cannot be found in the existing law Non IP Video Consistent with the existing terrestrial & satellite broadcasting Realize the quality equal to or higher than the existing broadcasting Copyright : Solutions can be found in the existing law Broadcasting providers prefer Non-IP
Double Play? Triple Play? Different players among POTS & Data Possible two different competition FTTH : Competition only for IP Unbundling Rule Potential Risk of Unbundling Demand for POTS & IP : Cream Skimming Service Environments Greater roll of VoIP A great impact of double play with non-ip video Single Play to Double Play (incl. VoIP)
Developing FTTH System Higher-speed PON:GE-PON (IEEE802.3ah) Background Learned from drastic price-down of MC Standardization & de facto standardization Many vendors from various industries Share the tech. & products of other market Requirements for GE-PON Upgradeability to Broadcasting Interoperability Open ONU to the Market in the near future Decrease in Capital investment Amount Price Competition to Functional Competition Service Menu of Customer Installation
Summary Competitive high-speed IP access market for mass users in Japan Competition leading a higher-speed market decreased charge drastically shifting from ADSL to FTTH Services : Single Play (IP) to Double Play (IP & non-ip Video) Quick service provision according to the user s demand : key to success
