Nokia 4A0-205 Exam - Topic 6 Question 48 Discussion

Which of the following statements is true about chromatic dispersion (CD)?
C) Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed.
A) Different channels have different bandwidth and this causes different CD performances.
B) The fiber attenuation changes along the fiber, and when the light crosses these differences the CD takes place.
D) The fiber attenuation introduces inter-channel interference.

Which of the following statements is true about chromatic dispersion (CD)?

Show Suggested Answer Hide Answer
Suggested Answer: C

The CPB (Commissioning Parameter Builder) application is used to generate the commissioning files for a Nokia 1830 Photonic Service Switch (PSS-1). The CPB application allows the user to create multiple commissioning files[1][2], which can be used to configure a variety of different features on the device. The CPB also allows users to view, edit and modify the commissioning files before they are uploaded to the device. The NSP (Network Service Platform) and EPT (Element Provisioning Tool) are used to manage the devices and network elements within the network, but do not generate commissioning files.

D seems off to me. Inter-channel interference is more about crosstalk, right?

Wait, I thought attenuation was the main issue, not just speed differences?

A is misleading. Bandwidth doesn’t directly cause CD.

D sounds familiar, but I can't recall if fiber attenuation directly causes inter-channel interference.

I practiced a question similar to this, and I think B is misleading because attenuation isn't the main cause of CD.

I'm not too sure about this one. The wording of the options is a bit tricky. I'll have to review my notes on chromatic dispersion before deciding.

Okay, I've got this. The key is understanding that chromatic dispersion is caused by the different wavelengths traveling at different speeds in the fiber. I'm confident C is the correct answer.

I'm torn between C and A. But I think C is the safer bet - different wavelengths traveling at different speeds is the crux of chromatic dispersion. Although, the idea of different channels having different bandwidths is kinda funny. Like, 'Hey, your red channel is hogging all the bandwidth!'

Definitely C. The other options are just trying to confuse us. Chromatic dispersion has to do with the wavelength-dependent propagation speeds, nothing else.

C is the clear winner here. The different wavelengths traveling at different speeds is the textbook definition of chromatic dispersion. No need to overthink this one.
