NEW QUESTION # 52
Which of the following statements about the main and backup channels of optical line protection is wrong?
- A. "Master-standby channel difference threshold (dB)" - used to set the difference between the main and standby optical ports of the board when the optical power difference reaches a certain value, it will be regarded as a signal failure (SF).
- B. "Initial Difference Between Active and Standby Channels (dB)"—the reference value used to set the optical power difference between the active and standby channels of the board.
