摘要
介绍了目前长岛数字电视传输系统的现状,创新地采用波分复用技术在一根光纤上双向传输数字电视信号及回传信号,项目实施以来取得很好的经济及社会效益,为解决缺乏光纤资源的海岛等特殊地区开通数字电视信号开辟了新的途径。
The author describes the digital television transmission system of Changdao. By WDM technique, the system fulfills bidirectional transmission in a single fiber for digital television signal and feedback signal. The project obtained desired economic and social profit, besides bringing forward a new approach for island areas where there is a shortage of fiber resources.
