Abstract
In this paper, single and hybrid amplifier configurations are implemented with FRA, SOA and EDFA amplifiersfor 160 channel DWDM systems at 10 Gbps& 25 GHz frequency spacing for L-band. These configurations are transmitted and measured over different distances for 40, 80, 120, 160, 200 and 240 km. The performance of single and hybrid optical amplifiers evaluated in terms of gain, output power, BER, eye height and Q factor. Among these setupsSOA-RAMAN-EDFA performed better than other optical amplifiers at all over the distance. It provides the highest output gain (53.06 to 50.84 dB), high output power (39.91 to 37.7 dBm), least bit error rate (-37.66 to -10.62 log of BER), Q factor (12.12 to 9) and good eye height (12.98 to 5.54 a.u.)for different transmission distance ranging from 40 to 240 km. These are all setups are arrangedwithout using any gain-flattening technique and receiver filters. Keywords-FRA, EDFA, SOA, DWDM, Transmission Distance,gain, Output Power, BER, Eye Height, Q factor.
