Fibre optic internet connections are now gaining at a greater rate than ADSL in Japan, according to recent research.
More than 5.35 million Japanese homes and businesses were using fibre-to-the-home (FTTH) as their main internet connection in March, Tokyo-based Multi Media Research Institute (MMRI) reported.
Japan's fibre subscribers will exceed 19 million by 2008, the firm predicted. "The number of FTTH subscribers doubled compared to the previous year," the research firm said.
"In contrast, [growth in] ADSL subscriptions, which had been the major factor of market expansion, declined considerably."
ADSL showed only a slight increase, from total subscriptions of 13.7 million in fiscal 2004 to 14.45 million in 2005.
Consultants Dittberner Associates announced recently that Japan added 2.5 million FTTH subscribers in 2005, making up 80 per cent of the entire FTTH market.
FTTH penetration in Japan is now growing at a rate of three million subscribers per year. The government wants to continue at this pace, eventually reaching 30 million homes.
Currently, half of Japanese households have some form of fibre internet connection available.
"Video, IPTV and other high bandwidth applications are driving demand for Passive Optical Network and Ethernet FTTH equipment all over the world," said Jeff Heynen, an analyst with US-based communications research specialist Infonetics Research.
"Passive Optical Network is very strong in the Asia Pacific region, particularly Ethernet Passive Optical Network, which is huge in Japan and will roll out in China soon as well."
日本光纤网络用户超过530万
最近的研究表明，在日本，光纤光学因特网连接正在以远超过ADSL的比例迅速增加。
东京基于多媒体研究协会报道说，3月份日本超过535万日本家庭和商业用户正在使用光纤到户（FTTH）作为他们主要的因特网连接。
公司预言，到2008年，日本的光纤用户将超过1900万。研究公司说，光纤到户订户的数目将会比过去那些年的总和的两倍。
“相比较而言，曾经是市场主要增长因素的ADSL签约用户的增长呈现出大幅度的下降。”
据国家财政统计，ADSL总签约用户数量从2004年的1370万到2005年的1445万只有少量的增长。
Dittberner 咨询协会最近发布通告，2005年日本增长的250万光纤到户用户，占据整个光纤到户市场的80％的市场份额。
在日本，光纤到户的突破是以每年300万的比例增长。政府希望这样增长继续下去，最终达到3000万的家庭用户。
现在，有一半的日本家庭认为光纤网络连接是有效的。
研究美国通信研究专家的分析家杰夫 海伦说，因为全世界的无源光学网和以太网的光纤到户设备都需要应用视频、IPTV和其他的高带宽。
在亚太地区，被动光学网是十分强大的。特别是以太网无源光学网络，在日本十分巨大，并将会很快的席卷中国。
