<p>A system and method for controlling the amplification of an optical data signal in an optical communication system having a plurality of optical fiber spans, each optical fiber span providing amplification to the optical data signal includes transmitting the optical data signal into a first optical fiber span at an input power level lower than a nominal power level. More than unity gain is provided to the optical data signal over each of at least a first group of the optical fiber spans such that the power level of the optical data signal after propagating through each of the plurality of optical fiber spans is higher than the nominal power level.</p> |
