An apparatus comprising an optical power splitter, an optical delay line coupled to the optical power splitter, an optical amplifier (OA) coupled to the optical delay line, and an adaptive injection current (AIC) controller coupled to the optical power splitter and the OA. Also disclosed is an apparatus comprising at least one component configured to implement a method comprising converting an optical signal into a voltage signal, calculating an amplitude correction value for the voltage signal, inverting an amplitude of the voltage signal, adjusting the amplitude of the inverted voltage signal according to the amplitude correction value, and converting the adjusted voltage signal into a current signal. Included is a network comprising an optical line terminal (OLT) comprising an optical receiver and an AIC controlled OA coupled to the optical receiver, wherein the AIC controlled OA provides optical power equalization for any upstream optical signals.
