Side Power Monitoring
Use the Side Power Monitoring subtab to view bar charts of the input and output spectrum on each optical side of the node. When you place the mouse over each wavelength in the bar chart, the power level and wavelength type are displayed. This feature is available on nodes that are installed with cards with Optical Channel Monitoring (OCM) capability.

Description
Bar Chart
Displays side power monitoring information.
The Side Power Monitoring panel is divided into Optical Side X subtabs, where X is the optical side. The number of subtabs is equal to the number of optical sides in the node. Each subtab displays two bar graphs.
The IN bar graph displays the optical spectrum at the input port (LINE-RX) of the side in the direction from the fiber to the node provided the OCM functionality is available on this port else the graph displays the aggregate signal spectral distribution on the first port in the signal flow (indicated in the title of the bar chart) that is downstream of the LINE-RX port where an OCM measurement is available (For example, in node using a booster and SMR card, the measurement is done on the EXP port of the SMR card).
The OUT bar graph displays the optical spectrum at the output port (LINE-TX) of the side in the direction from the node to the fiber provided the OCM functionality is available on this port else the graph displays the aggregate signal spectral distribution on the first port (indicated in the title of the bar chart) that is upstream of the LINE-TX port where an OCM measurement is available.
Note
Depending on the side layout, the LINE-TX port (output) and the LINE-RX port (input) of the card facing the fiber cannot measure the optical spectrum in a reliable manner if the OCM functionality is not available on these ports.
When you place the mouse over each wavelength in the bar chart, the power level and the wavelength type (local ADD/DROP or EXPRESS) are displayed as a ScreenTip.
 •
IN graph: The ScreenTip displays the destination side of each wavelength. The wavelength is either dropped locally or expressed to another side.
 •
OUT graph: The ScreenTip displays the source side of each wavelength. The wavelength is either added locally or expressed from another side.
