Bidirectional CATV system having losses for equalizing upstream communication gain

A gain variance and ingress reduction system reduces the overall ingress of interferers for an entire CATV system return transmission path and allows a reduction in subscriber terminal return transmitter power. The system places a calculated loss at each subscriber tap location. By placing these los...

Summary:A gain variance and ingress reduction system reduces the overall ingress of interferers for an entire CATV system return transmission path and allows a reduction in subscriber terminal return transmitter power. The system places a calculated loss at each subscriber tap location. By placing these losses at each subscriber location, the headend receives a more consistent return transmission path gain thereby reducing the terminal return transmitter power range requirement. In addition, the losses reduce return transmission path ingress.
