General
 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.

Technology Choices


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 Choices

APON is used very less in China

EPON dominates FTTH market
For home and small office with high-density
Provide POTS, Internet, IPTV, VOIP, and maybe CATV
Cheap and easy to evolve to NGN


GPON will be mainly used for FTTO
For medium size corporations with high-density
Provide POTS, Internet, IPTV, VOIP, leased lines

Make the best use of exiting SDH network resource

FTTH Target Market
 High end residence, especially the new builds, will be the starting
point for FTTH
 They are wealthy, seeking for modem life with advanced
technologies
High end
residence
 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
Business/CBD
 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
Internet bar
 Because of close location, PON is a good choice

FTTH 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 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

Deployment Model



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

Operation 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
