NEW QUESTION 120
A certain network is configured with SOM. When performing path performance analysis, the OSNR value of the downstream optical amplifier of the OCh path is higher than that of the upstream optical amplifier. What is the error of the following analysis ()?
- A. After the initial configuration of the SOM route is issued, the performance analysis is started immediately. If the SOM route is configured first in the OMS section at this time, the OSNR calculation is started first, and there is no basis for the previous OSNR calculation value, this phenomenon will occur
- B. Click "Analyze" on the "Path Performance Analysis" interface to restart the performance analysis to solve the problem

It takes about a few seconds to issue the SOM routing configuration for each OMS segment, and it takes a few seconds to configure the SOM routing existence time between each OMS segment. difference
- D. The calculation of the OSNR value of the first part of the OMS section where the OCH path is located is completed, and the calculation of the latter part has not been started. At this time, the performance analysis is started, and the new calculated value of the front part is reduced due to external reasons. This phenomenon will occur
