摘要
作为通信网络中最接近用户侧的宽带接入网成为制约通信网发展的瓶颈。因此,建立全数字化、高速化和宽带化的综合性接入网成为必然趋势。有线宽带接入网技术主要包括铜线接入技术、光纤接入技术和混合光纤同轴接入技术。宽带无线接入技术将与宽带光接入及其他接入技术融合成为下一代宽带接入网的主要技术。由于宽带无线接入网需要密布于用户临近的光纤网来支撑,因此FTTH+无线接入技术是未来发展的趋势。
The broadband access network become the bottleneck of communication network development.Therefore, establishing digital,high-speed broadband access and the comprehensive becomes a necessary tendency.Cable broadband access network technology including wire access technology ,optical fiber technology and HFC （hybrid access technology. Broadband wireless access technology and broadband access and other light as next-generation technology integration of broadband access technology.Due to the broadband wireless access to the fiber in user support near net,FTTH ＋ wireless technology is the future trend of development.
