Wait, 5676 kbit/s? That seems way too high for monitoring!

I thought it was 192 kbit/s, but I guess 64 kbit/s is also an option.

The 1510 nm wavelength is definitely the go-to for optical monitoring.

I feel like the answer might be 192 kbit/s, but I’m not confident. I remember discussing the importance of monitoring channels in class.

The 1510 nm wavelength seems familiar, but I can't recall if it was specifically tied to 64 kbit/s or something higher.

I think we practiced a similar question about WDM systems, and I want to say the answer was around 2 Mbit/s, but I could be mixing it up.

I remember studying the UU-T recommendation, but I'm not entirely sure about the exact bit rate for the optical monitoring channel.
