A. These windows are three different wavelength intervals where the WDM optical transmission occurs.

B. These windows correspond to three different minimum and maximum optical power levels used for optical transmission.

C. Different optical transmission windows correspond to different safety requirements and rules for the related lasers operating with these windows.

D. These three windows are three different angles of incidence of the light injected by the laser into the fiber.

A. No restrictions are imposed on the software release.

B. Only designs created with current and older releases can be opened and edited.

C. Designs created with an older release can be opened by a current release but cannot make changes.

D. Only designs created with the current release can be opened and edited.

A. Transport multiple signals transparently, onto several wavelengths, all together over one single fiber

B. Share a single signal among multiple fibers doing load balancing, and thus increasing the reliability of the optical transmission

C. Increase the bit rate of each client signal by spreading it over multiple wavelengths

D. Allocate different signals to different time slots

A. It allows the graphical visualization of the services deployed in the network with the details of the boards involved in the service.

B. It represents all supervised nodes grouped by alarm status (with a different color).

C. It allows context sensitive navigation and represents nodes and related physical connections with different colors. depending on the active alarms.

D. It automatically represents all nodes grouped by the location string assigned during the NE creation.

A. It is used to deploy new operators (administrator, observers, and so on) to access the platform.

B. It is used to create new network instances, such as physical connections, infrastructures and services.

C. It is used to import EPT files to deploy the network based on the EPT design.

D. It is used to deploy additional shelves to existing SWDM nodes.

A. The fiber attenuation introduces inter-channel interference.

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. Different channels have different bandwidth and this causes different CD performances.

A. Node synchronization is executed to test the reachability of a node

B. Full synchronization retrieves the correlated alarms from the node

C. Full synchronization retrieves all items from the node (NE parameters. Ports, Alarms, Internal Links, etc)

D. Node synchronization is executed to align the time of the node to the time of the NFM-T platform
