The invention is particularly useful in environments that include two level amplification, wherein the first level corresponds to each channel separately and the second level corresponds to the joint sum of all the channels.

Abstract: System and method to extend the data carrying capacity of a hybrid fiber cable (HFC) network by adding wideband RF signal capability above 1 GHz, and replacing the CATV amplifier devices with an improved type of Coax Domain Amplifier-Repeater (CDAR) device that, in addition to being a smart reconfigurable amplifier and cable signal diagnostic device, also segments the CATV cable portion of the HFC network into a series of smaller domains. The CDAR often alter RF signals from 5-865 MHz, while more freely passing RF signals over 1 GHz. Upstream capability is enhanced because the CDAR intercept 5-42 MHz upstream signals from each domain and convert to 1 GHz+ signals. Downstream capability is also enhanced because the CDAR can take efficiently encoded 1 GHz+ digital data, modulate it, and locally inject into each domain without crosstalk between domains. CDAR can use active cancellation, and active restoration techniques to improve performance.
