Performance characterisation of erbium doped fiber amplifier (EDFA) in optical transmission system / Noor Shahida Mohd Kasim

Erbium Doped Fiber Amplifier is a key challenge for today's optical transmission systems. The Erbium Doped Fiber Amplifier (EDFA) has its highest potential and better performances in comparison with other similar amplifiers when operating with a 980 nm or 1480 nm pump wavelength where gains in excess of 25dB and saturated output powers in the range of 20-25mW. This project presents a study of the Erbium Doped Fiber Amplifier (EDFA) performance characteristics over the optical transmission in term of gain, output signal power and amplified spontaneous emission (ASE). The design of Erbium Doped Fiber Amplifier (EDFA) is developed by using equipment ED-AMP OPTOSci. The results achieved are based on experimental setup by comparing the performance characteristics of EDFA while operating with and without 15dB attenuator. From the results, the performance characteristics of Erbium Doped Fiber Amplifier (EDFA) are applicable to improve and support the existing of optical transmission network. It have been confirmed that the pump power applied to Erbium Doped Fiber Amplifier (EDFA) sharply reduces due to absorption in Erbium doped fiber. Therefore, gain and ASE is strongly dependent on the pumping power and signal input power. This satisfied that the EDFA operation in saturation regime leading to maximum gain and minimum ASE.
