dear friends and researchers

i am simulating 1.25Gbps optical link for UWB over fiber where input is gaussian electrical pulses of 50ps width.the modulated gaussain pulses are converted into gaussian monocycle.the signal is successfully transmitted over 1km fiber for photodetection.at detector i am getting the required output but the BER analyser results are funny and strange.please check the screen shots (in attachment) of the simulation and results and let me know what is and where is the problem
