What are the functions of the "Cable Equalizer" and the "Pre-equalizer" in a line amplifier?

The Cable Equalizer allows to match the signal levels to be amplified at the internal stage of a broadband amplifier, thus preventing intermodulation at that stage. The Pre-equalizer generates an unbalance between high-frequency and low-frequency signals to compensate for the losses in the distribution network.

Reamplification for second distribution.
