Node synchronization is a process of keeping the NFM-T database in sync with the nodes in the network. The synchronization process will download all the items from the node, including NE parameters, ports, alarms, internal links, etc., to the NFM-T database. This ensures that the NFM-T database is up to date and the network is running efficiently.

Question 17
Which of the following statements is true about chromatic dispersion (CD)?
Options:
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.
Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed. This phenomenon is known as chromatic dispersion and causes light to spread out as it travels through the fiber over distance, leading to signal attenuation and distortion. The fiber attenuation does not introduce inter-channel interference, but it can cause attenuation of the signal. Different channels have different bandwidths, but this does not affect CD performance.
