Abstract :
In this paper, effectiveness of semiconductor optical amplifiers (SOAs) in tree-net in terms of increase in the number of users has been investigated. In the analysis, SOAs with (i) unsaturated gain, (ii) average gain saturation, and (iii) average gain saturation with gain fluctuations have been considered. Further, the results for the tree-net are compared with those for the star network. It is observed that tree-net supports more number of users than star for a given number of SOAs
