Dear All,
I’m working on designing DP-QPSK-MDM system.I used 100G-DP-QPSK system Example in Optisys but it’s not working well like demonstration in this tutorial.

100 Gbps DP-QPSK System with Digital Signal Processing

can anyone help me to run the attached system properly.

Best Regards,

        Hi. Can you ask me, in DP_QPSK system you used ideal optical fiber or not? I mean, did you check PMD and group velocity in fiber.
