Abstract: For the burst mode receiver design in the airborne optical network and multi user fiber optic network, this paper describes the characteristics and performance of a burst mode receiver that employs the nonlinear trans impedance pre amplifier. After building a model of this nonlinear pre amplifier and assuming the equivalent input noise, the receiver's BER performance of the linear and nonlinear pre amplifiers is calculated and compared. Moreover the authors also analyze the improvement of burst mode's BER and network transmission capacity when the nonlinear pre amplifier is used in the burst mode receiver.
