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.

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.

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
GSC: GSC: Standardization Advancing Standardization Advancing Global CommunicationsGlobal Communications 24 April 2006 18
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

GSC: GSC: Standardization Advancing Standardization Advancing Global CommunicationsGlobal Communications 24 April 2006 19
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
