Abstract: Nodes, amplifiers, and taps for an improved hybrid fiber-coaxial (HFC) network and methods for managing signals in an improved HFC network are shown and disclosed. The method may include receiving, at a node, a downstream optical signal in a higher- frequency band and a lower-frequency band separated from the higher-frequency band. The method may additionally include amplifying, at the node, the lower-frequency band by a magnitude different than that of the higher-frequency band. The method may further include combining, at the node, the higher-frequency band and the lower-frequency band into an output signal after the lower-frequency band has been amplified.
