SONET Thresholds (Physical Layer for OC-N)


(ONS 15600) Use the SONET Thresholds tab to provision the ONS 15600 OC-N optical power received (OPR), optical power transmitted (OPT), and laser bias current (LBC) thresholds. You can set the physical layer thresholds for 15-minute and 1-day periods.

Port

The port number.

LBC-HIGH

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

LBC-LOW

Displays the minimum threshold for the laser bias current; the default (15 min/1 day) is 50 percent.

OPT-HIGH

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

OPT-LOW

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

OPR-HIGH

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

OPR-LOW

Displays the minimum threshold for the optical power received; the default (15 min/1 day) is 50 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 decreases 3 dBm, the OPR decreases 50 percent.
