摘要：Analysis of the performance of star, tree and mesh topologies is made for successive distance between the nodes at the bit rate of15 Gbps . The number of users supported at different distances is calculated in terms of Quality Factor and BER for the input signal powerof -40dBm. An optimized Hybrid Raman-EDFA amplifier is used for post amplificion. Mach-Zehnder modulator at extinction ratio of 30dBwith symmetry factor of -1 is used for the modulation of signals. The spacing between the channels is taken as 0.1 THz with the line width of1 MHz. It is observed that Star topology is capable to support more users than other topologies for a distance of 6Km in terms of qualityfactor and BER.
