We investigated the performance of RAMAN-EDFA, RAMAN-EDFA-RAMAN, EDFA-RAMAN, EDFARAMAN-EDFA hybrid Amplifiers in C+L band for 16 channel WDM systems with each channel having data rate 2.5
Gbps at channel spacing of 100 GHz. The performance has been compared on the basis of different fiber length at
dispersion equal to 16.75 ps/nm/km in terms of Q- factor, BER and Gain. The results showed that EDFA - RAMAN -
EDFA provides the highest Q-factor, lowest BER and maximum eye opening up to distance of 100 km as compared to
RAMAN—EDFA, RAMAN-EDFA-RAMAN, EDFA-RAMAN hybrid amplifiers combination. EDFA-RAMAN is the
best alternative to RAMAN - EDFA in WDM system.
