True, plus Mach-Zehnder modulators have better control over dispersion. So I'm going with C too.

I read somewhere that Mach-Zehnder has superior performance in optical communication systems.

Really? I thought direct modulation, option A, would be better due to simplicity.

I'm leaning towards option C. Mach-Zehnder modulators are known for stability.

It's about how well the light source tolerates spreading out of light pulses.

I'm finding this question confusing. What even is dispersion tolerance?
