Haha, I'm going with option D just because it's the 'speed limit' for this signal. Who doesn't love a good 50 Gbaud rate?

Option A seems plausible to me. PDM-QSK should be able to support more bits per symbol per polarization than 8QAM.

Yeah, it seems like PDM-QSK is more efficient in terms of bits per symbol per polarization.

I agree, it makes sense that PDM-QSK would have that capability.

I think option B is the correct answer. The Gbaud rate for both 100G 8QAM and PDM-QSK is the same, which is 50 Gbaud.
