I thought they needed separate fibers for that.

I feel like this could be an error, but I can't recall the specifics. I need to review WDM concepts again.

I'm not entirely sure, but I remember something about needing separate wavelengths for each direction in WDM systems.

I think it's true because WDM stands for Wavelength Division Multiplexing, which means different wavelengths can be used simultaneously.

This sounds familiar; I practiced a question about bidirectional systems, and I think they do use different wavelengths.

Coercivity sounds right to me. That's the term I associate with the strength of a magnetic material's ability to hold its magnetization.

I believe deep learning is definitely one of the workloads, but I can't recall if HPC is included as well.

I'm feeling confident about this one. The query seems straightforward, and I think I can eliminate a few of the options pretty quickly. I'll double-check my work, but I'm optimistic I can get the right answer.
