The advantage of optical fiber to the home FTTH

    FTTH because of the use of optical fiber transmission medium, no noise, no radiation, EMI resistance is strong, the advantages of the communication system without being limited by the bandwidth, distance and get rapid promotion.As the growth of the national demand for bandwidth, have accelerated the trend of FTTH in recent years.According to the GARTNER report, published in the latest broadband users in the asia-pacific region grew by 50% in 2004 (from $2003 in 40.78 million to 2004, 61 million), one of Thailand's growth rate as high as 1456%, India grew by 236%, while JapanFTTH users increased from 2002 in 12000 to 2002 in 2002, 75% of Japanese operators can provide optical fiber to the home market, is expected in 2005 to one hundred percent of the optical fiber to the home of the coverage, FTTHsubscribers in Europe for 400000, 2003 is not Japanese, but significantly higher than that of the United States over the same period, and from now until 2008, European FTTH subscribers will be 60 ℅ growth each year.
    According to American Technology Futures Inc, forecast the broadband penetration will reach 75% by 2010.
    FTTH such rapid development momentum source and its huge market: 1) the P2P communication, namely symmetrical load, its application accounts for 50-70% of all network communication, 2) online games, the application has a huge market space, South Korea 90% of Internet users is the network game users, to the 2007 revenue is expected to more than $2 b, and the typical representative is fairly consumption ability have good education of adults.3) the remote medical treatment, can be fast and reliable network make the patients in the thousands of kilometers to get professional care, and can do face-to-face counseling or by video television in surgery get expert advice on site.4) network office, employees can freely flexible arrangement time, improve work efficiency.And reduce the construction cost of the company.
    In addition, it has quite attractive in terms of cost.1) FTTH active equipment price is 1.5 times of ADSL equipment only 2) twisted pair is the cost of wiring FTTH access 1/10 3) fiber with low failure rate, reduce the user maintenance (FTTH Vs DSL 2:7) 4) device of low power consumption, reduce energy expenditure
