Actual exam question for Huawei's H35-480_V3.0 exam
Question #: 43
Topic #: 3
[All H35-480_V3.0 Questions]

If the length of the CPRI optical fiber between a BBU and an RRU exceeds 150 m, you are advised to use a multimode fiber.

Show Suggested Answer Hide Answer
Suggested Answer: A

The Common Public Radio Interface (CPRI) is a standard that defines the interface between the BBU (baseband unit) and the RRU (remote radio unit) in a wireless base station. The BBU and the RRU are connected by an optical fiber cable, known as the CPRI optical fiber.

The CPRI optical fiber is used to transport the digital baseband signals between the BBU and the RRU. The distance between the BBU and the RRU can be up to several kilometers, but the standard CPRI specification only supports a maximum distance of 150m between the BBU and RRU using single-mode fiber. If the distance exceeds 150m, multimode fiber should be used to extend the distance between the BBU and the RRU.

Yeah, I heard the same thing! Multimode for over 150m.

I recall that multimode fiber is generally used for shorter distances, so I would lean towards False for this question.

I’m a bit confused. I thought multimode was for shorter distances, but maybe it changes at 150 m?

I practiced a similar question where the distance was a key factor, and I believe single-mode is preferred for longer runs, not multimode.

I think I remember something about multimode fiber being used for longer distances, but I'm not entirely sure if it's over 150 m specifically.

I'm pretty confident on this one. The question clearly states to use multimode fiber if the length exceeds 150 m, so the answer must be True.

Okay, I know multimode fibers can handle longer distances than single-mode. So if the length is over 150 m, the multimode fiber is the right choice.

I'm a bit confused on the difference between single-mode and multimode fibers. I'll need to review that before answering.

Hmm, this seems pretty straightforward. If the fiber length exceeds 150 m, I should choose the multimode option.

I'm pretty sure the recommended minimum for a high-availability search head cluster is 3 search heads, 1 deployer, and 3 indexers. Option B looks like the right answer.
