An optical link comprises a first optical amplifier having a first gain spectrum with a first gain ripple and a second optical amplifier having a second gain spectrum with a second gain ripple. A combined gain spectrum of the first and second gain spectra is substantially flat and has a gain ripple that is substantially less than either the first gain ripple or the second gain ripple over a particular wavelength range.
