多系统复用技术在广电信息网络中的应用

The Application of Multi-System Multiplexing Technique in Broadcasting TV Information Network Corporation

采用多系统复用技术对内蒙古赤峰市至敖汉旗之间的光缆骨干网络进行了扩容,采用该技术的光纤传输网络具有容量大、扩展方便、节约光纤资源等优点,尤其适用于光纤资源短缺的情况.同时,在SDH和1550数字电视光复用网络中使用了拉曼光放大器,有效地解决了SDH信号与1550数字电视信号之间的相互干扰问题.

By applying the multi-system multiplexing technique,the optical fiber backbone network between Chifeng and Aohan in Inner Mongolia is expanded.The optical fiber transmission network with the technique has advantages,such as bigger capacity,more convenient expansion,less optical fiber resource,etc.The multi-system multiplexing technique is especially suitable for the situation that it is short of optical fiber resource.Meanwhile,because of using Raman optical amplifier,the problem of mutual interference between the SDH signal and 1550 digital TV one has been solved effectively.
