1 OPTIMIST Workshop 2003 Broadband Access in Japan September 21, 2003 Hiromichi Shinohara Access Network Service Systems Labs.
2 10 Increase in the Demand of the Highspeed Internet Access in Japan HFC (CATV) 3.3 million ( 02.6) million( 02.6) 0.1 ADSL FTTH 70 thousand( 02.6)
3 Outline 1. High-speed Access Service and Market in Japan 2. Deploying Optical Access Systems 3. Obstacles to Prompt & Massive Deployment of FTTH and R&D to Overcome Obstacles 4. Access Service Market Trends and Developing System
4 10 1 Increase in the Demand of the Highspeed Internet Access in Japan HFC (CATV) 8.5 million ( 03.7) 2.3 million ( 03.7) 0.1 ADSL FTTH 531thousand ( 03.7) Peak speed of ADSL 1.5Mbps 8Mbps 12Mbps 24Mbps
5 What leads a higher-speed market? Killer Application? Government Policy! e-japan Initiatives Competition!!!
6 FTTH Service Providers in Japan - FTTH & FTTApartment National Provider East, West (Telecom) usen (Cable music broadcaster) Regional Provider TEPCO, K-Opti.com, QTNet, Energia com. (Electric Power Company & Its Subsidiaries) - FTTApartment KDDI (Telecom) HASEKO, NOMURA (Real Estate) EDGE (Internet Solution Provider)
7 FTTH-based Internet Access Service : B-FLET s FLET s Service FLET s ISDN, FLET s ADSL, B-FLET s A best-effort network service Fixed monthly charge users can access to their contracted ISP B-FLET s Line-up (Peak rate : 100Mbps) Business type Basic type Family type (EUR43/month, EUR50 incl. ISP) Condominium type (EUR23~28/month)
8 Outline 1. High-speed Access Service and Market in Japan 2. Deploying Optical Access Systems 3. Obstacles to Prompt & Massive Deployment of FTTH and R&D to Overcome Obstacles 4. Access Service Market Trends and Developing System
9 Employed Architecture FTTH FTTH ONU ONU SS PDS Condominium Type Service : FTTBasement FTTH ONU ONU ONU ONU SS SS/PDS ADS
10 Preferable Conditions for FTTH in Japan Shorter Loop Length Feeder Cable : High Penetration (by, Power Suppliers) Distribution Cable, Lead-in Cable : Mainly Aerial, Easy to Replace or overlay Higher Population Density in Cities
11 Deploying Optical Access Systems SCM-PON (Video) + STM-PON (POTS) for CATV video transmission(1997) STM-PON (10Mbps, shared access) for Wide-LAN & B-FLET s (2000) ATM-PON (156 and 622Mbps) for Leased Line (1997) MC (100M) for B-FLET s (2001) B-PON (622/156Mbps) for B-FLET s (2002) SCM-PON (Video) + B-PON : trial (2002)
12 B-PON : Broadband IP Access System ONU 100BASE-TX G cm Wavelength Allocation 2-stage splitting MAX:32 622Mbps 156Mbps OLT PDS/ Ether-IF 100BASE-TX Local IP NW G Shared access using DBA (Dynamic Bandwidth Assignment) function (G.983.4)
13 Outline 1. High-speed Access Service and Market in Japan 2. Deploying Optical Access Systems 3. Obstacles to Prompt & Massive Deployment of FTTH and R&D to Overcome Obstacles 4. Access Service Market Trends and Developing System
14 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
15 ADSL vs. FTTH 1$=117JPY Fixed Monthly Charge Initial Charge $60 $ $ $150 $ $ $100 $20 $10 $0 with POTS w/o POTS ADSL (12M) FTTH $50 $0 Engineer Install Customer Install ADSL (12M) FTTH
16 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
17 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
18 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
19 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 Number of WTs : 200 WT
20 Outline 1. High-speed Access Service and Market in Japan 2. Deploying Optical Access Systems 3. Obstacles to Prompt & Massive Deployment of FTTH and R&D to Overcome Obstacles 4. Access Service Market Trends and Developing System
21 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
22 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)
23 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
24 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
