QUESTION 14
Which of the following statements about the Wavelength Tracker (WT) capability is TRUE?

Wave Keys are originated by optical amplifiers.

WT uses a unique identifier based on a pair of numbers encoded by Raman amplifiers into each service wavelength direction.

WT is compatible with other vendor domains, but the user must make sure that Wave Keys are unique on the crossed domains.

WT uses a unique identifier based on a pair of numbers encoded by Optical Transponders OTs) into each service wavelength direction.
