Abstract
Raman amplification is added to a transmission system to provide an in crease in power budget allowing for a four-fold upgrade in capacity ei ther by TDM or WDM. Here, a TDM upgrade from 2.5 to 10 Gb/s and a WDM upgrade from a single 10 Gb/s channel to four channels of 10 Gb/s each were experimentally verified with an improvement in the power budget of 7.4 dB, Raman gain is an attractive upgrade method for installed sy stems requiring no changes to the fiber span.
