DefinitionsFTTN - fiber is terminated in a street cabinet up to several kilometers away from the customer premises, with the final connection being copper.

FTTC - this is very similar to FTTN, but the street cabinet is closer to the user's premises; typically within 300 m.

FTTB - fiber reaches the boundary of the building, such as the basement in a multi-dwelling unitFTTH - fiber reaches the boundary of the living space, such as a box on the outside wall of a home.

FTTP - this term is used in several contexts: as a blanket term for both FTTH and FTTB, or where the fiber network includes both homes and small businesses.

Summary

Structure

Architecture

• Copper cables must be 100 meters or less

• That means you need a powered telecom closet on each floor

• Fiber only needs one telecom closet per building

Fiber vs. Copper•Copper cables

•That means you need a powered telecom closet on each floor

•Fiber only needs one telecom closet per building

Cost of Fiber v. Copper•Copper components are cheaper, but you

need more total equipment and it uses more space

•If you include everything, fiber may even be cheaper than copper

Pros and Cons

Pro:• FTTH offers a full service suite, and long-term capability• Municipalities accept a long payback time, for future benefit• FTTH is competitive in new builds, with user costs mortgaged• There is enormous pressure for standards: FSAN and SMF• Outside plant has no electronics: high reliability & upgradable• System prices are dropping fast, making this more competitive• The optics content per subscriber is large ( ~ 45% of total)

Con:• The economics are weak now, as costs exceed yearly revenue• FTTH is just starting, and system variations proliferate• Standards are divergent among Asia, Europe, USA

Market AnalysisThe greatest rate of FTTH adoption is occuring in Asia.

About 21% of homes in Hong Kong have FTTH and South Korea has 19.6% of homes connected to FTTH.

• The main reason for the huge penetration in Asia, as opposed to the US, is that the governments of countries such as Japan and South Korea are specifically promoting this technology as a part of their national strategy.

• The United states had about a 1.3% penetration in 2007, but does have a large amount of fiber optic cables in the ground left unused from the dot com bust.

• Many of the telecom companies were laying cable at a faster rate than they were getting customers, but now these companies can start utilizing this installed base thanks to the renewed growth of demand from consumers.

• In 2007, the number of US households with FTTH doubled from 2006.

World Wide FTTH DeploymentsJapan• Japan has the largest and the most successful fibre-to-the-home

(FTTH) deployments in the world till date. The Japanese Ministry of Public Management estimates that by March 2006 there will be 7.73 million households connected to the Internet by means of the optical fiber in Japan. While the Japanese carriers have initially adopted ATM based BPON architecture and the growing demand for higher bandwidth has forced them to look for alternative option. Now Japanese carriers have started embracing EPON solution also called as GE-PON.

USA• In US, majority of the carriers are launching FTTH services with

BPON architecture. With the development and availability of GPON, many of the carriers have planned for migration to GPON architecture.

Korea• In Korea, 74% of the population already has a broadband

connection to the Internet and main telecommunications companies are investing heavily in the optical infrastructure in order to maintain their competitive edge.

Europe• In Europe broadband access is getting more and more attention. The

“eEurope 2005” program was launched by the European Council in 2002. Its agenda is primarily concerned with promoting broadband Internet in the member countries.

China• In recent years China has been catching up with the leaders. Chinese

telecommunication carriers are still at the stage of testing and promoting FTTH without actual commercial applications. Throughout the promotion stage, FTTx, as just one of several broadband access technologies, has faced fierce competition from xDSL. In 2004, a more complete FTTH demonstration project was undertaken in order to verify FTTH technology and product maturity, and serve as the foundation for future FTT applications. In particular, the Optics Valley of China in Wuhan city is nearly complete demonstration of an FTTH testing point.

India• Ministry of Communications & Information technology has recognized the

need to increase the broadband penetration in the country. Broadband policy-2004 puts FTTH as the one of the major broadband options. Many carriers have already deployed fiber to the curb. Finalization of FTTH drop cable specifications by TEC is the first step in this direction. Private and public telecom operators are already in the process of conducting trials on broadband on FTTH network.
