有线电视电缆的介绍和特点

 

介绍：

CATV的全名是“社区天线电视”。 有线电视电缆用于宽带传输。 它不同于其他以太网物理层使用的基带传输。 宽带布线系统可以将频带划分为不同的频谱，然后通过不同的频带提供不同的服务。 这种技术已广泛用于有线电视广播中，由于每个频道占用不同的频带，因此不能在同一条电缆上同时提供多个电视频道，因此它们不会相互干扰。

 

 

 

 

特性 ：

CATV的特点是多重通信和双向通信。 将来，CATV系统可能会使用光纤而不是同轴电缆来传输信号。 由于光的波长短于高频波的波长，因此使用光传输信号可以增加很多传输容量，并可以实现高传真率的效果。 由于光纤的出现，CATV的性能将进一步发挥。
