  1. By adopting qam ( quadrature amplitude modulation ) modulation, we have researched and implemented a high - speed data broadcasting system compatible with dvb ( digital video broadcasting ) standard in the past years, and integrated and applicated the system into sdh / hfc ( synchronous digital hierarchy / hybrid fiber coax ) network for the first time in china

    經過多年的研究，開發出了符合dvb標準、採用qam調制方式的陽光網高速數據廣播系統，同時在國內首次實現了基於sdh hfc網路的高速數據廣播系統集成應用。
  2. Hfc access network technical specification. hybrid fiber coax neteork

    接入網技術要求?混合光纖同軸電纜網
  3. Hybrid fiber coax hfc

    混合光纖同軸網
  4. Hfc hybrid fiber coax

    混合光纖同軸
  5. Hfc ( hybrid of fiber and coax ) network is a competitive means to support wide varieties of video, voice and data services. the thesis describes and analyzes the system framework, frequency assignment and signal modulation schemes of hfc. recently hfc and adsl are aggressive among broadband access technologies

    本文對hfc網的系統結構、網路拓撲、頻譜分配方案和業務信號的調制方式等進行了詳細的闡述和分析，並且全面地比較了hfc和adsl的優缺點，總結出hfc具有較高的性價比，是我國寬帶接入網的優選方案。
  6. The history ^ culture ^ external opportunities and threats ^ internal strengths and weaknesses of l - g have been analysed deeply by using the basic theory and analysis methods of strategic management. there existing external opportunities, such as : broadband network construction, hfc ( hybrid fiber - coax ) upgrading reconstruction, catv digitization. also there existing threats, such as : uncertainty policies and substituted technologies. only a correct company strategy what fully utilize the external opportunities and avoid the internal weaknesses, can a company is promoted to develop

    本文利用戰略管理的基本理論和分析方法，對中國有線電視的現狀和發展、行業內的競爭和競爭對手的優劣勢做了客觀真實的對比研究，得出了對外部環境給公司的發展提供了巨大的發展機會，如：寬帶網建設、 hfc雙向網改造、有線電視的數字化、 「三網融合」 、有線電視網的多功能開發等，同時也有政策的不確定性和技術風險等威脅。
  7. Hfc ( hybrid fiber - coax ) - a cable or network using both coaxial and fiber optic technology. since fiber is more expensive than coaxial, hfc makes for a more cost - effective solution

    混合光纖同軸電纜- -一種既使用同軸技術又使用光纖技術的電纜或網路。因為光纜費用較高、混合光纖同軸電纜通常能夠達到節省費用的目的。
  8. With the development of conventional catv system and the completion of its equipment ' s tow - direction upgrading hfc hybrid fiber coax has become an important way to provide the two - direction integrating broadband service to users

    隨著傳統有線電視網路及其設備雙向改造的完成， hfc （ hybridfibercoax ） ，即光纖同軸混合網已成為向用戶提供雙向寬帶綜合業務的重要途徑。
