目前全球FTTH的发展现状是日本发展最快,被认为已进入大规模发展阶段;美国紧跟其后,成为继日本之后的第二大市场;欧洲主要国家由于ADSL和ISDN使用较多,FTTH在很长时间内发展较慢,但目前已经开始升温。各国FTTH发展的动因和特点基本一致,主要是市场和技术竞争、业务需求、政府推动,各国根据自己人口分布、城市格局等情况采取不同的发展策略和技术方案。未来几年,全球FTTH的发展格局不会有大的变化;但其成本将进一步下降,GPON和EPON技术将成为主流。
At present, the current status of global FTTH development is Japan’s fastest growing, is considered to have entered the stage of large-scale development; the United States followed, becoming the second largest market after Japan; major European countries due to more ADSL and ISDN, FTTH Slower development for a long time, but now it has started to heat up. The motives and characteristics of FTTH in all countries are basically the same, mainly due to market and technological competition, business needs and government promotion. All countries adopt different development strategies and technical solutions according to their own population distribution and urban pattern. The next few years, the global FTTH development pattern will not have major changes; but its cost will decline further, GPON and EPON technology will become the mainstream.
