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

  • Large scale deployment, easy for planning, deployment and maintenance

High end residence

  • 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

Business/CBD

  • 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 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

GSC: Standardization Advancing Global Communications


Gsc11 06 joint 12

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

GSC: Standardization Advancing Global Communications


Gsc11 06 joint 12

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

Summary

  • 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
