Which of the following statements best describes the definition of PCT?

• A. tool supporting nodes' automatic provisioning on NFM-T
• B. tool to validate internal fiber connectivity on CDC-F 2.0 nodes.
• C. tool supporting zero-touch power management on PSS-32 equipment
• D. tool supporting external links autodiscovery on NFM-T

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

WDM allows transmission systems to:

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

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

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

What is a trail?

• A. An entity to encapsulate a low order signal into a high order container
• B. transparent transport of a client signal
• C. link between end points to increase the power budget of the optical link
• D. physical link between two optical amplifiers
