A. The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth. B. The OSNR is defined as the ratio between the transmitted optical power and the received optical power over 1 km of fiber including both signal and optical noise. C. The OSNR is defined as the ratio between the optical signal power (including noise) and the optical noise power over a specific spectral bandwidth. D. The OSNR is the ratio between the optical output signal power and the optical input signal power of the device being analyzed.

A. The systems are displayed on the CPB panel, however they cannot be individually selected as they need to run all together B. The systems are displayed on the CPB panel and they can be individually selected C. 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 D. The systems are not reported on CPB, but only through the Equipment Manager

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. Dispersion compensation module (DCM) B. Optical transponder (OT) C. Wavelength router (WR) D. Static filter device (SFD)

A. It represents all supervised nodes grouped by alarm status (with a different color). B. It automatically represents all nodes grouped by the location string assigned during the NE creation. C. It allows context sensitive navigation and represents nodes and related physical connections with different colors. depending on the active alarms. D. It allows the graphical visualization of the services deployed in the network with the details of the boards involved in the service.
