一、有线电视综合信息网 在深圳有线电视综合信息HFC网已经成为深圳市信息高速公路的重要载体之一。它是以有线电视台为总前端,各住宅小区建立分前端,总前端通过光纤与各分前端相连,各分前端通过光纤和各相应的光节点相连,所有的信息通过光电转换,用同轴电缆送到千家万户。目前我们的有线电视综合信息网随着HFC双向传输技术的运用,并结合通信技术和计算机应用技术的推广,在综合信息网上既可传输有线电视信号,
First, cable television integrated information network in Shenzhen Cable HFC network integrated information has become an important carrier of Shenzhen City, one of the information carriers. It is the cable television station as the total front-end, the residential district to establish sub-front, the total front-end fiber connected to the various sub-front, the sub-front through the optical fiber and the corresponding optical nodes connected to all the information through photoelectric conversion, with coaxial cable Send to millions of households. At present, with the application of HFC bidirectional transmission technology and the popularization of communication technology and computer application technology, our CATV network can not only transmit cable television signals on the integrated information network,
