Abstract
A submarine optical repeater that shares optical pump power in multiple gain stages such that approximately the same wavelengths of optical pump is provided to each of the gain stages. Also, tilt control mechanism may adjust gain dependency on wavelength by adjusting the amount of optical pump power delivered to the optical gain stages. Residual optical pump power from both forward and backward Raman amplification may be used to power corresponding optically pumped amplifiers.
