Performance of a 32 Channels WDM System using Gain Flattened EDFA
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2017, Vol 4, Issue 8
Abstract
The gain flattening of erbium doped fiber amplifier (EDFA) is essential for their application in wavelength division multiplexing (WDM) system. This paper attempts to design and analyse a 32 channels WDM system using EDFA in the wavelength range of 1546 to 1560 nm with channel spacing of 0.4 nm. The analysis is made for the data rate of 10 Gb/s of NRZ signal. The gain flattening of EDFA in such system is achieved through EDFA’s pump power and input power variation. Results show that the gains are flattened within 43.6 ± 0.8 dB with noise figure about 7.38 dB at pump power of 600 mW and input power of -34 dBm using optimized erbium doped fiber of 6.2 m length. The performance analysis in terms of BER, eye diagram and Q factor shows satisfactory results
