LBC-HIGH

Laser bias current–maximum. Maximum

Numeric percentage of the baseline value

 

 

threshold for LBC.

 

 

 

 

 

 

 

LBC-LOW

Laser bias current–minimum. Minimum

Numeric percentage of the baseline value

 

 

threshold for LBC.

 

 

 

 

 

 

 

OPT-HIGH

Optical power transmitted–maximum.

Numeric percentage of the baseline value

 

 

Maximum threshold for OPT.

 

 

 

 

 

 

 

OPT-LOW

Optical power transmitted–minimum.

Numeric percentage of the baseline value

 

 

Minimum threshold for OPT.

 

 

 

 

 

 

 

OPR-HIGH

Optical power received–maximum.

Numeric percentage of the baseline value

 

 

Maximum threshold for OPR.

 

 

 

 

 

 

 

OPR-LOW

Optical power received–minimum.

Numeric percentage of the baseline value

 

 

Minimum threshold for OPR.

 

 

 

 

 

 

 

Set OPR

Setting the optical power received (OPR)

Click Set.

 

 

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.

 

 

 

 

 

 

 

Types

Sets the threshold values of alerts that

TCA (threshold crossing alert)

 

 

trigger an alarm or TCA response. To view

Intervals

Sets the time interval for collecting
