Which factors determine the optical signal-to-noise ratio (OSNR) of the receiving end to a certain extent After the signal transmission in the WOM system is transmitted over a certain distance, the "oSNR" of the receiving end of the optical signal-to-noise ratio is reduced to a certain extent. Which of the following is the main cause?

AUse EDFA. ).

BUse of multi-density multiplexers and multiplexers.

CDo not use new optical fibers.

Fiber attenuation, huh? I bet the person who designed this fiber link needs to go back to Fiber Optics 101.

I bet the person who wrote this question has been spending too much time in the dark fiber closet. The answer is obvious!

But wouldn't using EDFA also help improve OSNR in the WOM system?

I agree with Polly, high optical fiber attenuation can definitely reduce OSNR.

Hmm, I was thinking it might be the use of EDFA, but I guess that's not the case. Fiber attenuation makes the most sense.

I agree with Elden. Fiber attenuation is the culprit here. EDFA, multiplexers, and new fibers aren't the issue.

New optical fibers wouldn't make a difference in this scenario.

Yeah, using EDFA or multiplexers wouldn't affect it as much.

Fiber attenuation is definitely the main cause of reduced OSNR.

The answer is clearly D. Optical fiber attenuation is too high. That's the main factor that reduces the OSNR at the receiver.
