Q1:
Is it possible to mix PSS-24x and PSS-8x shelves In an SWDM configuration?
○
A
Yes, as both can be equipped within the same node○
B
No, as they are not compatible and cannot be used within the same node○
C
Yes, but the PSS-24X shelf must be configured as a master○
D
Yes, but the PSS-8X shelf must be configured as a master

Q2:
Which of the following statements is true about chromatic dispersion (CD)?
○
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.○
C
Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed.○
D
The fiber attenuation introduces inter-channel interference.

Q4:
What is the meaning of first, second, and third window in the optical fiber propagation context?
○
A
These windows correspond to three different minimum and maximum optical power levels used for optical transmission.○
B
These windows are three different wavelength intervals where the WDM optical transmission occurs.○
C
These three windows are three different angles of incidence of the light injected by the laser into the fiber.○
D
Different optical transmission windows correspond to different safety requirements and rules for the related lasers operating with these windows.
