id="article_content">成本较低的以太网无源光网络(EPON)接入解决方案目前特别受到以中日韩为代表的亚洲国家的欢迎，市场调研公司Dell'Oro Group提供的全球接入市场预测报告<a href="http://display.oecr.com" target="_blank" class="relatedlink">显示</a>，亚太地区部署的FTTx接入中约94%采用了EPON技术，亚太地区PON市场有望从2009年的2280万用户快速增长到2014年的9450万用户，年复合增长率达到33%。<BR><BR>博通亚太地区运营商市场发展经理Jay Teborek表示，未来数年将会是PON网络迅猛发展的黄金时段，其驱动力将主要来自视频点播、高清IPTV、高速互联网、3G/4G移动回传和<a href="http://b.oecr.com/company" target="_blank" class="relatedlink">企业</a>业务等对高速宽带互连的追求。<BR><BR>上述判断得到了来自中国FTTH大会相关数据的印证：对中国EPON FTTx用户而言，每个家庭平均宽带需求将由2010-2012年的20M-30Mbps攀升至2012-2015年的50M-100Mbps。因此，如何在各种应用程序所占带宽剧增的环境下，帮助用户改善网络体验，成为运营商和OEM厂商面临的共同难点。<BR><BR>“中国正在积极部署EPON，以向高密度房屋即‘多住户单元(MDU)’提供高速宽带互连，实质性的政策支持包括下一代广播网(NGB)和三网融合计划。”Teborek分析认为，“这些计划表示大型CATV/MSO(多种服务提供商)将在今年或明年进入EPON市场，并将导致MSO市场出现重要的结构性改变。”<BR><BR>由于能够在每个ONU上支持多个逻辑链路标识符，博通最新10G EPON单芯片BCM55030可通过一个共用基础设施，高质量地传输住宅业务、关键任务、企业业务以及基站回传。这意味着，时间敏感的移动回传和同步数据可以与视频、语音和互联网数据共用网络，而不会增大延迟、数据丢失或降低服务质量(QoS)，使得该解决方案非常适用于设备制造商以及服务提供商在人口密集的城区提供相应服务。<BR><BR>Teborek强调说，BCM55030的另一个关键卖点在于其拥有“业界最高的器件集成度、超低功耗和非常小的占板面积”，从而为企业路由器、多住户单元系统、家庭网关等用户端设备提供了一个经济实惠的平台。BCM55030无需外部存储元器件，它支持全新IEEE 802.3av 10G EPON标准和中国电信等中国运营商所制定的有关EPON标准，完全支持10G EPON和1G EPON共存。此外，BCM55030还支持10G/10G对称和10G/1G非对称工作模式，以及2.5G Turbo EPON，适用于4G/LTE移动回传。<BR><BR>与此同时，博通还将触角伸向了1G EPON市场。其中，占全球1G EPON市场40%份额的中国成为重中之重。据悉，Broadcom BCM53600是“世界上集成度最高的1G EPON单芯片”，使运营商能用最少的组件快速部署比萨盒式应用，完整的单芯片系统包括集成的交换器、PHY、CPU、EPON MAC、话音DSP和<a href="http://opticaldesign.oecr.com" target="_blank" class="relatedlink">软件</a>开发工具包(SDK)。此外，该系列器件还支持IPv6，多种接口有助于灵活、平滑地向多种技术和部署方案过渡，如VDSL、VoIP、10G EPON和GPON。 <DIV><FONT color="#808080" size=2><IMG
