[advertise]广告[/advertise]12/13/2009, According to some marketing analysis, mainland China is the largest EPON market around the world now. Huawei has replaced Mitsubishi to be the No. 1 EPON equipment supplier. At the same time, tens of EPON equipment manufactures emerge in China. Today you can easily find a Chinese EPON ONU supplier from Alibaba.com. But that company may don’t have its own manufacturing ability. Three main service providers of China have organized several inter-operation tests since year 2006. From those tests, we can know many names of real EPON ONU manufactures in China. You must already knew the big names of Huawei, ZTE, Fiberhome, UTStarcom, Huawei 3Com (today’s HP), Salira. You should also know the names of some other local manufactures like Nokia-Siemens Ocean Broadband (www.obroadband.com.cn), YOTC(www.yotc.com.cn), Datang, GWTT(www.gwtt.com), GKTEL(www.gktel.com.cn)，Baniantech，D-Link, Xunfeng（/www.xunfeng.com）, Twsz（www.twsz.com）, Dare（www. dare-tech.com）. Not like those big suppliers who have wide product portfolio, these local EPON manufactures often focus on access products. Some of them like GWTT, GKTEL, Xunfeng are traditional PDH equipments suppliers, some of them like YOTC, Dare, TWSZ are start-ups in this field. Investors of YOTC include YOFC, the largest fiber manufacture in China, Sumitomo from Japan and Changjiang Communication, a public company in Wuhan. About Dare and TWSZ, both of them extended from DSL modem products to PON products several years ago. In EPON field, the real pioneer is Salira. In fact, Salira educated the first group of EPON engineers in this field in China. For example, Baintech and Ocean Broadband were founded by some former Salira engineers. Baintech once built one of the first EPON trial networks in Zhenjiang, Jiangsu Province. Salira is part of Hitachi today, their contribution to China’s EPON market not only is how many products they sold, but also how many engineers they provided, how much they educated this market.
