Wait, can L1 encryption really affect latency?

L1 encryption sounds important for security, but I doubt it would help with latency on a long link like this.

Low-noise amplifiers seem like a good option for improving signal quality, but I don’t recall if they directly affect latency.

I remember practicing a question about FEC, and I think soft-decision FEC can reduce latency, but I’m not confident it’s the best choice here.

I think DCM-free amplifiers might help with latency, but I'm not entirely sure how they compare to the others.

DCM-free amplifiers? I'm not familiar with that term. I'll need to look it up to see if that could be a viable solution for reducing latency.

I think the key is to reduce the signal degradation over the long distance. Low-noise amplifiers might be a good choice to boost the signal and improve the SNR.

Okay, let's see. I'm pretty sure the answer has to do with the physical layer, not encryption. Soft-decision FEC could help, but I'm not sure if that's the best option here.

Hmm, this seems like a tricky one. I'll need to think carefully about the factors that affect latency in long-distance links.

Emailing the current state documentation and an agenda ahead of time seems like a smart way to set the stage for the workshops. That way, everyone can come prepared to discuss the future state.

Reviewing and approving timesheets seems like a good way to catch potential fraud. I'm not sure that would be the least effective either.

D) L1 encryption? Really? I don't think that's gonna do anything for the latency. Maybe if we're trying to keep the data secure, but not for reducing latency.
