Abstract
The placement of optical amplifiers in WDM star fibre-optic networks h as been considered. Both postamplifier and preamplifier configurations have been investigated. The number of users supported by the topology has been obtained when reflection noise and amplifier gain saturation (cross-saturation) are present. The effect of extinction ratio has al so been considered. In general the analysis shows that the preamplifie r arrangement is better than that of the postamplifier.
