DEMO QUESTIONS

Q1:

What is the definition of OSNR?

A: 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.

B: The OSNR is the ratio between the optical output signal power and the optical input signal power of the device being analyzed.

C: The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth.

D: The OSNR is defined as the ratio between the optical signal power (including noise) and the optical noise power over a specific spectral bandwidth.

Correct Answer: C

Q2:

Which application generates the commissioning file(s)?

A: NFM-T

B: NSP

C: CPB

D: EPT

Correct Answer: C

Q3:

Which statement is correct about the NFM-T network map?

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

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

Correct Answer: C

Q4:

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.

Correct Answer: C

Q5:

What is the definition of OSNR?

A: 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.

B: The OSNR is the ratio between the optical output signal power and the optical input signal power of the device being analyzed.

C: The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth.

D: The OSNR is defined as the ratio between the optical signal power (including noise) and the optical noise power over a specific spectral bandwidth.

Correct Answer: C
