A method for correcting power tilt in an optical signal includes tapping off a representative portion of an optical signal and separating the representative portion into a first signal and a second signal. The first signal includes a first wavelength band and the second signal includes a second wavelength band different from the first wavelength band, wherein each wavelength band includes more than one channel. The method also includes detecting a power level of the first signal, detecting a power level of the second signal, and comparing the power levels of the first and second signals. The method further includes determining a power tilt for the optical signal based on the comparison and adjusting an amplifier gain based on the power tilt.
