Upper and lower alarm thresholds are set for the transmit and receive power of the optical module on the interface. The NCS 1001 provides optical amplification, protection switching, and Optical Time Domain Reflectometer...

If it does exceed, replace the TRM of the transmitting node with a TRM with less output power or install an optical attenuator to avoid receiver overload. The value of this attenuator must be at least the
To help an optical module keep stably running, set the optical power of the optical module at least 3 dBm more than the receiver sensitivity or to a middle value between the receiver sensitivity and
If it does exceed, replace the TRM of the transmitting node with a TRM with less output power or install an optical attenuator to avoid receiver overload. The value of this attenuator must be at least the
You can set optical power alarm so that the device generates alarms if the transmit or receive power of an optical module exceeds a threshold. An alarm may indicate that the optical module is faulty.
If the transmit optical power is low (Current TX Power has a smaller value than Default TX Power Low Threshold), the transmit signal strength on the local optical module is too low. This may cause low
With safety control mode enabled, when the OTS controller receives optical power less than the rx-low-threshold, the transmit of that controller turns off (ALS) until the condition clears.
Upper and lower alarm thresholds are set for the transmit and receive power of the optical module on the interface. When the transmit or receive power of an optical module exceeds the upper alarm
At the destination, the different optical signals are demultiplexed again into separate optical signals. Wavelength spacing is about 1 nm so allowing for a lot of wavelengths in the useful spectrum of the
To ensure normal communication between two optical interfaces, check for transmit and receive power alarms after the two interfaces are connected using optical modules and optical fibers.
You can set optical power alarm thresholds using commands. When the transmit or receive power of an optical module exceeds the alarm threshold, an alarm is generated, indicating that the optical module
