Introduction

• Broadband services have been popularized rapidly.• Especially, FTTH has been a “key player” in Japan.

• Goals– Economical service fee– Popularize multimedia applications, i.e., streaming video– Popularize high speed Ethernet technologies for telecom and home

infrastructure– Save CapEx and OpEx for LS and TS by introducing VoIP

• Environment– Easy installation of aerial fibers on telephone polls– Improvement of performance of user devices, e.g., PC


• Transitions in the Number and the Percentage of Internet Users in the Population in Japan

Migration of PON Architectures

• Type of PON


Popularity of IP Centric Communication

• Applications over FTTH

IP Centric Communication over FTTHIP Backbone

Service providers

VoIP technologies

IP Video technologies-Broadcasting TV-Interactive TV

High performance data communication

Highly reliable and QoS controllable IP transmission

It is feasible to converge all FTTH applications on IP as economical and sophisticated solutions


PON System for Ethernet Services

• Examples of implementation of GE-PON system

GE-PON ONU-IEEE802.3ah compliant-Performance: 100% throughput-UNI: 100Base-T or 1000Base-T

GE-PON OLT-IEEE802.3ah compliant-Performance: 100% throughput-SNI: 1000Base-T-No. of Ports: 16

Requirements-Standard compliant-Low cost-Ethernet interfaces with high performance to apply any applications on FTTH


Key Technology for PON


• Requirements for future trends(1) Real time, QoS guarantee, & Bi-directional services for Video phone and

conference systems

(2) Large volume bulk data transmission for P2P using high bit rate (e.g. more than 30Mb/s per user )

(3) Secure and seamless communication with intelligent terminals

Large transmission capacity Intelligent protocol processing

Summary

• FTTH is rapidly growing in Japan• PON technology is the key to realize FTTH economically• DBA (Dynamic Bandwidth Allocation Mechanism) is the

key to utilize bandwidth of PON• Ethernet PON is the best match for all IP network trend• Ethernet PON can be used for NGN with its QoS

mechanism
