Amplification apparatus, device, and method for a tap of a cable communication network

An amplification apparatus for a tap of a cable communication network, the amplification apparatus comprising:

• interface circuitry for exchanging a first version of a shared signal with a first component of the cable communication network, wherein the shared signal is based on a frequency spectrum comprising at least a first frequency band and a second frequency band,
• interface circuitry for exchanging a second version of the shared signal with a second component of the cable communication network;
• amplifier circuitry configured to selectively amplify the first frequency band of the frequency spectrum of the shared signal, such that the first frequency band is amplified in the second version of the shared signal;
• and
• a low-pass filter and at least one high-pass filter, wherein the low-pass filter is configured to at least partially block the first frequency band, and wherein the at least one high-pass filter is configured at least partially block the second frequency band,
• wherein filter characteristics of the low-pass filter and of the at least one high-pass filter of the amplification apparatus are chosen such that, within a transition frequency band partially overlapping the first and the second frequency band, a shift in a frequency response of the low-pass filter occurs in an opposite direction to a shift in a frequency response of the at least one high-pass filter.
