Optics Thresholds
(ONS 15310-CL, ONS 15310-MA, ONS 15454, and ONS 15600) Use the Optics Thresholds tab to provision alarm/alert threshold values. For a list of ONS nodes and cards that support this subtab, see Provisioning.
Note
Not all PM thresholds apply to all cards.
 
Port
Displays the port number.
LBC-LOW
Displays the minimum threshold for the laser bias current.
LBC-HIGH
Displays the maximum threshold for the laser bias current.
OPT-LOW
Displays the minimum threshold for the optical power transmitted.
OPT-HIGH
Displays the maximum threshold for the optical power transmitted.
OPR-LOW
Displays the minimum threshold for the optical power received.
OPR-HIGH
Displays the maximum threshold for the optical power received.
Set OPR
Setting the optical power received establishes the received power level as 100 percent. If the receiver power decreases, then the OPR percentage decreases to reflect the loss in receiver power. For example, if the receiver power decreases by 3 dBm, the OPR decreases 50 percent.
Types
