Pulse shape

[muhammad jawad]

Dear friends

hope you all are fine in life

i am simulating 10Gbps optical for UWB monocycle pulse generation.At Tx side i am using user defind PRBS at fixed pattern “1000 0000 0000 0000” where 1 comes after 16 bits.By using visualizer at the MZM,i am getting the true shape that a bit 1 after every 16 bit(screen shot is attached) but at point where monocycles generate,i get a train of uwb monocycle pulses rather it should be like as same pattern as at TX side that is bit “1” after fifteen “0” bit(screen shot is attached)
what is the problem and why i am getting a train of UWB monocycle pulses(as shown in attachment “expected output”) instead of one monocycle for bit 1 and then after 15 “0” bit another monocycle?
plz help me and clear my point

Can you try from minimum bit rate first. You can start from 622Mbps then 1GHz and proceed to a higher speed.

My Dear Taiwo

thanks a lot for your kind response.I did not start from lowest bit rate,how i am going to consider your suggestion which seems good.
thanks again for replying out of your definite busy schedule
i will let you after checking the simulation with low bit rate
regards
