Abstract :
This paper presents the applications of Semiconductor Optical Amplifiers (SOAs) in subcarrier multiplexed (SCM) fiber radio systems with theoretical and experimental approach. In these multichannel analogue optical fibre links high signal to noise ratio and at the same time low non-linear distortion are required. The paper works at the optimal position of the in-line optical amplifier, an alternative concept with semiconductor optical amplifier branching stages is suggested and the optimal operation point is studied. The SOA gives favourable properties as a multifunctional device according to the experimental studies, hence it offers a fine solution for the add/drop functions problem.
