Hold up, is this a trick question? I feel like I'm being pranked with these answer choices. Where's the 'All of the above' option when you need it?

I think the answer is D) The Gbaud rate is 50 because PDM-QSK typically has a lower baud rate compared to 8QAM.

Option D is a joke, right? 50 Gbaud? That's like, a hundred years ago in the world of high-speed communications. I'm not falling for that one.

But wouldn't a higher order modulation like PDM-QSK support more bits per symbol?

Option C is just wrong, everyone knows each symbol supports 1 bit per polarization, not 2. Come on, guys, get it together!

Yeah, option C is definitely incorrect. Each symbol only supports 1 bit per polarization.

Option B seems plausible, but I'm not convinced it has the same Gbaud rate as 100G 8QAM. These modulation schemes can be tricky.

Option A sounds legit, but I'm not sure if it supports more bits per symbol per polarization than 8QAM. Gotta do some research on that one.

Let me know what you find in your research about the comparison with 8QAM.

The Gbaud rate for 100G PDM-QSK is 50, so option D is not correct.
