summary


GeneralGeneral

There are total 4.05M km cable have been installed in China

160×10Gb/s and 80×40Gb/s DWDM system have been used in commercial network

ASON, MSTP have been deployed in core and Metro network.

Access network is still the bandwidth bottleneck.

General




summary


Two major FTTH architectures: P2P and PON. P2P good for: enough CO space, subs sparsely located and

their distances to CO vary, and/or high scalability requirements in b/w.

P2P SDH for big and medium corporations P2P Ethernet for homes and small businesses

PON good for: limited CO space, subs are closely located and their distances to CO similar, low scalability in # of users and b/w.

Both P2P and PON be used in China.

Technology ChoicesTechnology Choices


APON is used very less in ChinaEPON dominates FTTH market

For home and small office with high-densityProvide POTS, Internet, IPTV, VOIP, and maybe CATVCheap and easy to evolve to NGN

GPON will be mainly used for FTTOFor medium size corporations with high-densityProvide POTS, Internet, IPTV, VOIP, leased linesMake the best use of exiting SDH network resource

High end High end residenceresidence

Business/CBDBusiness/CBD

Internet bar Internet bar

High end residence, especially the new builds, will be the starting point for FTTH

They are wealthy, seeking for modem life with advanced technologies

Large scale deployment, easy for planning, deployment and maintenance

Most users in business building/CBD requires high bandwidth and integrated services. This type of users generates high ARPU

They need triple play plus TDM leased lines

They are more concerned of stability and quality,not sensitive to cost

Internet bar are very popular in China, they usually closely located to each other and need lot of b/w

ADSL does not meet b/w requirement, FTTH is a good solution

Because of close location, PON is a good choice

FTTH Current DeploymentFTTH Current Deployment

By end of 2005, about 10K commercial FTTH subscribers and another 10K in field trials. By end of 2006, may be 120K.

The biggest FTTH network has about 1000 subscribers Beijing, Wuhan, Shanghai and Hangzhou are major cities with

FTTH deployment, more than 20 cities are involved. China Telecom and China Netcom are two major carriers in

FTTH deployment and operation Almost all the deployments are using GEPON The major equipment vendors include Fiberhome, UTstarcom,

ZTE, ASB and Huawei About 75% of over all FTTH deployment using Fiberhome’s

equipment

FTTH ApplicationsFTTH Applications

Multiple play

POTS voice: provide RJ11 interface with built-in IAD

VoIP voice: provide Ethernet interface for IP phone

Internet: Ethernet inteface

IPTV: Ethernet interface to a STB

CATV: CATV cable interface

TDM leased line: E1/T1

Because of regulation restrictions, most deployments do not

provide CATV

IP phone is not usually provided due to its less popularity


By telecos and CATV providers– Same as that for the existing BB access networks– Invest once and profit in a long term

By telecos, CATV providers and house builders– House builders responsible for deployment, deployment

cost counts into into house price– Telecos and CATV responsible for operation and

maintenance– Multiple parties share the profit

By residential service providers (RSP)– RSP responsible for network operation and maintenance – Telecos responsible for providing exit port and b/w– Services provided by multiple-parties

Deployment ModelDeployment Model


By telecos and CATV providers– Enough operation experience– No interworking and inter-billing problem– Hard for triple-play

By residential service providers– Easy for integrated planning and deployment of the

overall information platform

– Evolution to NGN

– Encourage competition

– Network resource sharing

– Tailong model in Chengdu is the first attempt

SummarySummary

Massive deployment will start in 2007

China’s FTTH market is huge

FTTH still too expensive than existing technologies in the near future, but the cost will drop rapidly

“China Telecom Law” to be issued soon and will be promoting three network convergence

Field trial and deployment shift from big cities to medium cities , then every cities
