Another keynote speaker yesterday was Mr. Mao qian, director of optical communication sub-committee of China telecommunication committee. His speech was about FTTH and M2M network. According to him, China has already had 20 million FTTx subscribers, which exceeds Japan's scale. But among those FTTx subscribers, very few of them are FTTH subscribers. In the future, the coming triple play policy will further promote China's FTTx development. And for the future Mache to Machine (M2M) application in home, FTTH will be the only choice to connect this home M2M network to Internet.
