随着有线电视光纤传输技术的发展和普及,HFC(光纤同轴电缆混合网)网络已经成为有线电视传输的一种标准形式。HFC不仅解决了有线电视大范围高质量传输的难题,而且改善了网络结构,使CATV网络成为信息高速公路的基础框架,为将来构建宽带综合功能网展现了美好前景。
With the development and popularization of CATV optical fiber transmission technology, HFC (Hybrid Optical Coax Network) network has become a standard form of cable television transmission. HFC not only solves the problem of large-scale high-quality transmission of cable television, but also improves the network structure, makes the CATV network as the basic framework of the information superhighway and presents a bright future for building a broadband integrated functional network in the future.
