ITU-T

• ITU Consent in May 2005 (Approved in

February 2006)

• Multiple profiles defined to address regional

and application specific requirements

• ADSL/ 2/ 2+ interoperability
• Worldwide subscribers to Digital Video

Recording (DVR) services will rise by a factor

• f seven between 2005 and 2010
• Polymer Opt ical Fibre (POF) solut ion for

Home Networking?

ITU-T

• Very high speed data up to 1 Gbit/ s to

home and businesses

• Low cost due to fibre and CO interface

shared by several customers

• Maintenance cost reduction due to no

electronics between CO and customers

• Multiple applications including data (IP),

video and voice (triple play)

Highlights from Presentation 2 “PON”

ITU-T

• Distribution of High Definition TV(HDTV) is

a key application for broadband access networks

—Cable TV system (traditional type, HFC is typical) —FTTH - high speed IP (Video distribution using TDM, Ethernet technology)

• Critical issues in Home Networking and

Transport

—Domain control and Digital Rights Management (DRM) —Quality of Services (QoS) definition

Highlights from Presentation 3 “Cable TV”

ITU-T

• Field trials have indicated its feasibility

and identified further study items

• Global harmonisation required to promote

it as global standard (i.e., such as equipment/ system interoperability, common frequency band allocation, etc.)

Highlights from Presentation 4 “W iMAX”

I TU-T W orkshop “NGN and its Transport Netw orks“ Kobe, 2 0 -2 1 April 2 0 0 6 6

ITU-T

• Distribution of High Definition TV(HDTV) is a key

applicat ion for broadband access net works

• Increase PON bandwidth by using higher

transmission rate or WDM technology

• Increase PON reach by using optical amplifier
• Higher PON splitter ratio (more users per PON) by

using optical amplifier
