摘要
40Gibt/s系统的市场需求已经明朗,技术已趋成熟,成本已接近启动门限,规模应用指日可待;自动交换光网络的市场需求已经呈现,技术已经基本成熟,规模应用即将开始;城域电信级以太网技术已经逐渐具备公用电信网所要求的必备功能和性能,成为城域汇聚和接入层面的重要发展方向;基于无源光网络的FTTx将逐渐成为宽带接入的主要选择,针对不同应用场景需要部署不同的方案。EPON已经成熟,GPON技术趋向成熟,产业界需要加大推进力度。
Market demand for 40Gbit/s is clear now, relevant technologies are mature, cost is close to the threshold of taking off and mass deployment will start soon. Market demand for ASON is showing up, relevant technologies are mature in major parts and mass deployment will start soon. Metro cartier grade Ethernet technologies already have necessary features and performances of public telecom applications and become major development direction for metro consolidation and access layers. PON based FTTx gradually becomes the major option for broadband access technologies, however, different applications are employed in different scenarios. EPON is mature and GPON is close to mature, which still needs more attention and promotion of industries.
