Optics Thresholds


Use the Optics Thresholds tab to provision alarm/alert threshold values.

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; the default (15 min/1 day) is 50 percent.

LBC-HIGH

Displays the maximum threshold for the laser bias current; the default (15 min/1 day) is 150 percent.

OPT-LOW

Displays the minimum threshold for the optical power transmitted; the default (15 min/1 day) is 80 percent.

OPT-HIGH

Displays the maximum threshold for the optical power transmitted; the default (15 min/1 day) is 120 percent.

OPR-LOW

Displays the minimum threshold for the optical power received; the default (15 min/1 day) is 50 percent.

OPR-HIGH

Displays the maximum threshold for the optical power received; the default (15 min/1 day) is 200 percent.

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 is 6 dBm and decreases to 3 dBm, the OPR decreases by 50 percent.
