Theoretical limits in noise figures for a long haul transmission line based on lumped amplification are compared with distributed amplification. A reduction of approximately 60% of the required number of pump power stations is achieved. The distributed optical amplification is provided by an erbium doped fiber and comparisons of aluminum and germanium as codopant materials are shown. The pump power consumption and noise figure are analyzed with respect to the background loss.
