Abstract

Methods and systems for an intelligent tap with dynamically configurable amplifier gain. The intelligent tap includes a filter configured to process a signal received from a service provider system via a hybrid fiber-coaxial network, an amplifier connected to the filter, the amplifier configured to apply a feedback controlled gain value to the signal to generate an output signal, where the feedback controlled gain value is based on a comparison of a target signal strength to a sampled output signal strength, and a signal strength measuring component connected to the amplifier in a feedback loop, the signal strength measuring component configured to sample the output signal, and compare a signal strength of a sampled output signal to the target signal strength to generate the feedback controlled gain value, where application of the feedback controlled gain value maintains the output signal at a constant amplitude pursuant to the target signal strength.
