无论是在分配上还是在操作运行上,正向信号(下行)和回传信号(上行)之间有着很大的区别,而每Hz固定功率法是用于双向HFC网络中回传信号功率分配的一个非常方便的方法。
There is a big difference between the positive (downlink) and return (uplink) signals, both in distribution and in operation, and the fixed power per Hz method is used for the power distribution of the return signal in a bidirectional HFC network A very handy way.
