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

  1. Different channels have different bandwidth and this causes different CD performances.
  2. The fiber attenuation changes along the fiber, and when the light crosses these differences the CD takes place.
  3. Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed.
  4. The fiber attenuation introduces inter-channel interference.

Answer(s): C



How does a Raman pump work in the 1830 specific implementation?

  1. The amplification is done simultaneously for all channels as they enter the board.
  2. As the incoming signal power increase, the gain of the amplifier is reduced.
  3. The pump light travels in the same direction of the signal, amplifying it while it flows in the fiber towards the following node.
  4. The pump light travels in the opposite direction of the signal to be amplified, amplifying it while it arrives from the adjacent node.

Answer(s): D



WDM allows transmission systems to:

  1. Transport multiple signals transparently, onto several wavelengths, all together over one single fiber
  2. Increase the bit rate of each client signal by spreading it over multiple wavelengths
  3. Share a single signal among multiple fibers doing load balancing, and thus increasing the reliability of the optical transmission
  4. Allocate different signals to different time slots

Answer(s): A



When monitoring the quality of the received signal in WDM, an open eye indicates:

  1. Low noise
  2. High distortion
  3. High jitter
  4. Presence of high inter-symbolic interference

Answer(s): D

The main thing about this exam dump is that the PDF is not free. And that is what I needed. So I had to pay for that but they offer 50% discount if you buy 2 or more exams.
