TY - JOUR AU - Dr. Sanjeev Dewra, Rajpreet Singh, PY - 2015/08/28 Y2 - 2024/03/28 TI - Analysis of Star, Tree and Mesh Optical Network Topologies for successive distance between nodes Using Optimized Raman-EDFA Hybrid Optical Amplifier JF - International Journal of Engineering and Computer Science JA - int. jour. eng. com. sci VL - 4 IS - 08 SE - Articles DO - UR - http://ijecs.in/index.php/ijecs/article/view/3347 SP - AB - <p><em>Analysis of the performance of star, tree and mesh topologies is made for successive distance between the nodes at the bit rate of 15 Gbps . The number of users supported at different distances is calculated in terms of Quality Factor and BER for the input signal power of -40dBm. An optimized Hybrid Raman-EDFA amplifier is used for post amplificion. Mach-Zehnder modulator at extinction ratio of 30dB with 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 of 1 MHz. It is observed that Star topology is capable to support more users than other topologies for a distance of 6Km in terms of quality factor and BER. &nbsp;</em></p> ER -
