Huawei H31-311_V2.5 Exam - Topic 3 Question 57 Discussion

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?
A) Use EDFA. ).
B) Use of multi-density multiplexers and multiplexers.
C) Do not use new optical fibers.
D) Optical fiber attenuation is too high.

High attenuation definitely reduces OSNR, no doubt about it.

Wait, are we really not using new optical fibers? That sounds risky!

Multi-density multiplexers can complicate things, not sure they help.

I’m a bit confused about the role of multiplexers. Do they contribute to noise, or is it mainly the fiber itself that affects OSNR?

I feel like we had a practice question about the effects of fiber quality on signal loss. High attenuation definitely seems like a likely culprit here.

I’m not entirely sure, but I think using EDFA might actually help boost the signal rather than reduce the OSNR.

I remember studying how optical fiber attenuation can really impact the OSNR, especially over long distances.

I'm pretty confident I know the answer to this one. Optical fiber attenuation is the main factor that reduces OSNR over distance in a WDM system.

The use of EDFA and multiplexers could definitely impact OSNR, so I'll need to think through how those components work in the system.

Okay, I think the key here is to identify the main cause of OSNR reduction after signal transmission. The options provide some good clues to consider.

Hmm, I'm a bit confused about the relationship between OSNR and optical fiber attenuation. I'll need to review that concept before answering.
