B. These windows are three different wavelength intervals where the WDM optical transmission occurs.
C. These windows correspond to three different minimum and maximum optical power levels used for optical transmission.
D. These three windows are three different angles of incidence of the light injected by the laser into the fiber.
Question 2
How are the EPT systems related to NFM-T when CPB is performed?
A. The systems are not reported on CPB, as this Is transparent to the user and the whole network is validated and provisioned in one step
B. The systems are displayed on the CPB panel and they can be individually selected
