1 Geneva, Switzerland, 22 September 2012 FTTx in Japan: Past, Present, and Prospects for the Future Ken-Ichi Suzuki, NTT Access Network Service Systems Laboratories, NTT Corporation Joint ITU/IEEE Workshop on Ethernet - Emerging Applications and Technologies

2 Geneva, Switzerland, 22 September NGN service has almost covered over Japan Population coverage 90 % Number of FTTH user exceeds to 20 M. Market of FTTH will be matured. Development of optical broadband network will be facing a new era. Progress of Broadband Infrastructure in Japan

3 Geneva, Switzerland, 22 September The number of FTTH subscribers exceeds 22 Million now. It is expected to exceed 30 million by the end of March Progress of Broadband Service in Japan (1) Press materials, Ministry of Internal Affairs and Communications of Japan, Quarterly data on the number of subscribers, etc., of electrical communication services in Japan,

4 Geneva, Switzerland, 22 September Gbps high speed services are being provided at the same price as 100/200 Mbps services in some area for both SFU and MDU. Progress of Broadband Service in Japan (2)

5 Geneva, Switzerland, 22 September NTT has a share of 74.2 % and million subscribers of FTTH services. NTT has over 13 million IP Telephony (Hikari-denwa (0ABJ)) service subscribers via FTTH Services. NTT starts to provide MDU FTTH services using optical fiber wiring to connect each residence. Progress of Broadband Service in Japan (3)

6 Geneva, Switzerland, 22 September Keep connectivity will be easily possible anytime and anywhere Possible to get personalized information whenever we want Optical and wireless converged broadband will be an important key role Cloud & Broadband Optical Services

7 Geneva, Switzerland, 22 September Portable wireless router (Hikari-portable) provides optical services high mobility. Need to offload the mobile traffic (wireless) to optical access (wired). Broadband services is personalized by means of various smart handset Broadband Optical Service with High Mobility

8 Geneva, Switzerland, 22 September Some value added services are provided via broadband optical access systems. Power consumption visualization service helps customers to plan power savings. Other Broadband Services

9 Geneva, Switzerland, 22 September Advanced video services equipment and changing ways of watching video services will spur further bandwidth demand. mobile traffic expansion issue would be solved by optical access. Expected Next-generation optical access as a significant platform for future broadband ubiquitous services Requirement of Broadband Access

10 Geneva, Switzerland, 22 September Operators keep CAPEX reduction strategy for strength of financial basis Higher capacity network will lead to increase of network Cost reduction per user to the same level as the existing system is key CAPEX/OPEX reduction

11 Geneva, Switzerland, 22 September G/10G-EPON demonstration using OLT/ONU integrated with MAC-SoC Power saving operation using ONU sleep function QoS evaluation of multiple services with different priorities 10G-EPON with SoC demonstration

12 Geneva, Switzerland, 22 September km uncompressed HD video signal transmission using 10G-EPON Development of wide-area Dynamic Bandwidth Allocation (DBA) Remote performance monitoring of PON extender located outside plant 10G-EPON Field Trial

13 Geneva, Switzerland, 22 September Other requirements 1G/10G coexisting Energy efficient Long reach/wide area and high split ratio Synchronous10G-EPON Application to future mobile backhaul will be an attractive candidate Frequency synchronization is realized by using Synchronous Ethernet technology implemented into 10G-EPON system Time synchronization of PON is realized by 802.1AS implementation Highly reliable 10G-EPON High reliability is needed for higher-capacity and larger-splitting PON Progress of keep connection services i.e. video distribution, real-time gaming Cost-effective redundant configuration can upgrade and replace OSU Interoperable 10G-EPON SIEPON/G.epon compliant with some additional specification. The use of some interoperability test program for SIEPON/G.epon

14 Geneva, Switzerland, 22 September Conclusions and Recommendations The number of FTTH subscribers exceed 22.3 million now in Japan. That is expected to exceed 30 million by the end of March Development of optical broadband network will be facing a new era Mobility and Cloud 10G-EPON is ready for commercial that has flexible system configuration and its feasibility was confirmed by some demonstrations and a field trial.
