Question 1

Where is the OPS card equipped to provide the optical channel protection?

A : Between the transponder and the amplifiers

B : Between the filters and the amplifiers

C : Before the transponder, on the clientside, towards the external device

D : Between the transponder and the filter

Answer: C

Question 2

Which of the following applications is related to Wavelength Tracker tool?

A : Collecting logs related to possible issue affecting a wavelength path

B : Tracking the protection path for a specific wavelength

C : Tracing the end-to-end wavelength optical power

D : Correcting errors related to wavelength inconsistencies

Answer: C

Question 3

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

Answer: A

Question 4

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.

Answer: C

Question 5

What is the main function of an optical amplifier?

A : Demodulating the incoming signal

B : Compensating for optical power attenuation

C : Compensating for chromatic dispersion

D : Compensating for attenuation through an optical-electrical-optical amplification

Answer: B
