摘要
介绍克拉玛依市有线电视网络总体概况和以光节点为单位进行数字电视整体转换的方式,并以此形成了模拟电视信号和数字电视信号在总前端至分前端之间使用不同光纤同频传输、通过光纤跳接的有线数字电视整体转换技术方案。
This article introduced the overview of the CATV network of Karamay and the integral the digital television transformation method which takes the fiber node as the unit.And thus formed the technology scheme of the integral transformation,in which the fiber jumper is adopted and the Analog TV signal and Digital TV signal use different optical fiber co-frequency translation between the front-end and sub head-end.
