Study on the performance characteristics of erbium-doped fiber amplifier for G and L-band / Mohamed Arshaad Sobrattee

In this project, the performance characteristics of Erbium-doped fibre amplifier (EDFA) in C-band (1520- 1555nm) and L-band (1560- 1610nm) are theoretically investigated. Several configurations were designed in order to determine these characteristics. The components involved in the set-up configura...

From the results obtained from simulation of these configurations, it was found that bi-directional exhibits the highest signal gain as well as appropriate noise figure (NF) value, which falls in the acceptable range for EDFA which is 6 to 8dB [6].

The performance characteristics include usable input power (Pjn), signal gain (in dB), NF (in dB) and the pump power at which gain saturation start to occur.
