BER Evaluation in the cascade of 2R BMORs in the presence of Atmospheric Turbulence

Abstract

Burst mode optical Regenerators (BMORs) have the ability to deal with input powers having large variations. This makes them a suitable candidate to be used in hybrid FSO systems due to the presence of atmospheric turbulence in the channel. With the aid of numerical modelling, the impact of a 2R BMOR cascade on the BER of a hybrid FSO-Fiber system has been investigated and the results have been compared to a continuous mode OR (CMOR) cascade. The effect of amplified spontaneous emission noise has also been incorporated in the model and its interaction with atmospheric turbulence has also been presented.
