Abstract

In this paper, we investigated the number of nodes supported in optical system at different crosstalks with minimum optical input power for Ring, bus topologies using optical cross connect and with protection schemes in these topologies at 10 Gb/s in the presence of hybrid optical amplifier. It is found that in ring topology, more than 20 nodes are supported at -10 dBm signal input power and 8 nodes are supported at -20dBm signal input power for -30dB crosstalk. In bus topology, 16 nodes are supported at -10 dBm signal input power and 4 nodes are supported at -20dBm signal input power for -30dB crosstalk. The number of nodes supported in case of -50 dB and -70 dB crosstalks are more than 20 in both the bus and ring topology..
