PM-QPSK Modulation

[Muhammad Usama khanParticipant]

Hi Everyone,

Currently I am using Optisystem version 7.
I want to work on PM-QPSK but unable to find PM-QPSK transmitter and receiver.
Another thing for 100Gbps QPSK system, how we can simulate BER of whole system using one BER analyzer?
Thanks in advance.

Dear Muhammad,
There is an example (112Gbps Coherent DP-QPSK_Trans with DSP.osd) in OptiSystem Example Library that can be used for your design. It is located at the following link.
