Hi,
How to generate Quadrature Dual Polarization-Duobinary signal? If any one generated please provide the details.
Please provide the snapshot of circuit diagram.
The attached project is Dual Polarization Duobinary system.
Since the DSP for Duobinary modulation format hasn’t been finished yet, the DSP and BER measurement parts have to be built using our Matlab component.
Mine is lower version of Optisystem.So please provide Circuit diagram and important parameters in image format.
Attached is a picture of a Duobinary dual polarization system.
Hi,
How to generate DP-QDB(Dual Polarization Quadrature Duobinary) Modulation?
(Above attached paper is about DP-DB but to get DP-QDB, 90 degree phase shifter has to be added after one of MZM and before Power combiner.If i am going wrong on this method please correct me)
How to get Constellation diagram as shown in the attached paper?
Please provide me assistance.
Try something like in the attached pic!
Please reply
Thank you damian for your reply.
Got the constellation diagram what i am expecting.
What ever i mentioned method in previous post for DP-QDB generation(90 degree phase shifter has to be added after one of MZM and before Power combiner) is correct or not?
Please provide your feedback.
Thanks and Regards

There is a 90 degree phase shift in the X coupler which generates the two optical signals. The second output port is always 90 degrees out of phase with the first output port, so it should not be necessary.
