A redriver chip for an active copper cable is provided includes: an input signal detection module, configured for detecting a signal amplitude of an input signal; an amplitude gain control module, configured for: performing amplitude control based on a first adjustable gain so as to obtain an intermediate signal; an equalization control module, configured for: performing gain control based on a second adjustable gain, to a gain of a high-frequency part of the intermediate signal relative to a low-frequency part, so as to obtain an output signal. The chip is configured for: amplifying in equal proportions a low-frequency part of the output signal relative to a low-frequency part of the input signal and a high-frequency part of the output signal relative to a high-frequency part of the input signal.
