In a scenario where non-convergence OTU boards process standard SDH signals, both site A and site B are WDM sites, and the R_LOS alarm is detected on the client side of the OTU board at site A. After an alarm is processed on the WDM side of the OTU board, the REM_5F alarm is reported on the client side of the downstream site B. Then, site B transmits the signals to its downstream client device and reports the R^LOS alarm to the client device.

• A.TRUE
• B.FALSE

The decrease of optical power when light passes through a passive optical component is called the____.

You should analyze higher-severity alarms such as critical alarms first, and then lower-severity alarms such as major alarms.

• A.TRUE
• B.FALSE

In an OTN (80 wavelengths in full configuration), the input optical power of an amplifier ranges from -16 dBm to 4dBm. If 10 wavelengths pass through the amplifier, what is the nominal multiplexed-wavelength input optical power of this amplifier (the noise impact is not considered)?
