The Design And Implementation Of FuZhou HFC Cable Television Network

Fuzhou, the existing cable television network transmission capacity of small, aging equipment, poor process line installation, cable transmission using multi-stage cascade amplifier series active transmission, network security, reliability, less important is not conducive to real-time to carry out operations, the impact of service quality, and no longer meet the needs of radio and television business and the development of integrated services, so the imminent transformation of the network.HFC has brought new technology solutions. HFC network using fiber-to-service areas, access to users in the "last 1 km" the use of coaxial cable, it is more reasonable and effective use of the current maturity of advanced technology into digital and analog transmission as a whole, set-in-one photoelectric, At the same time, higher quality and more channels of traditional analogue radio and television programming, high-speed data transmission services and value-added services to a wide range of information.Papers by Fuzhou HFC cable television network design and planning analysis, combined with the status quo of network resources, business demand forecast and the research of key technologies HFC network, a transmission network in Fuzhou, China Radio, Film and Television applications HFC technology master plan design. HFC paper analyzed the network topology, optical fiber links, coaxial links, on the transfer box set, node settings, network reliability is given the classification of specific recommendations for network operation conditions of the equipment and materials specific requirements. For the technical characteristics of HFC networks, an analysis of papers at the same time after the introduction of HFC network management network influence on the downlink system, return system, such as network planning and optimization aspects of the analysis.Finally, the paper design based on the completion of the Fuzhou Radio HFC network transformation results, and proposed a network maintenance management and building development.
