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.
Claims17
A method of managing signals in a hybrid fiber-coaxial (HFC) network, comprising:
- receiving, at a node, a downstream optical signal, wherein said received downstream optical signal having a higher-frequency band and a lower-frequency band, wherein said lower-frequency band is at least partially overlapping in frequencies with said higher-frequency band, wherein said higher-frequency band has frequencies that are greater than any frequencies in said lower-frequency band, wherein said node separates said lower-frequency band from said higher-frequency band, where the separated lower-frequency band includes frequencies included in said separated higher-frequency band;
- amplifying, at the node, said lower-frequency band by a magnitude different than that of the higher-frequency band for said partially overlapping frequencies;
- and
- combining, at the node, the result of said amplifying said higher-frequency band and the lower-frequency band into an output signal that is transmitted from said node.
