光纤/同轴电缆混合(HFC)宽带用户网络的现状 随着人类社会逐步进入信息社会,全球范围内开展的“信息高速公路”建设极大地推动了通信、广播电视技术的高速发展。目前,先进的干线电信网络技术—高速大容量SDH光纤通信系统和异步转移模式ATM交换技术已经成熟,进入了商用推广阶段。但在用户网络建设方面目前占主导地位的依然是传统
The status quo of broadband optical fiber / coaxial cable (HFC) subscriber network With the gradual entry of human society into the information society, the construction of “information superhighways” worldwide has greatly promoted the rapid development of communications, broadcasting and television technologies. At present, advanced trunk telecommunication network technology - high-speed and high-capacity SDH optical fiber communication system and asynchronous transfer mode ATM switching technology have matured and entered the commercial promotion phase. However, the dominant position in user network construction remains the tradition
