Field DescriptionField Name
Displays the magnitude of the laser bias power setting current,
in milliamperes. The laser bias provides direct modulation of
laser diodes and modulates currents.
Laser bias current
Displays the laser output power, in milliwatts (mW) and
decibels referred to 1.0 mW (dBm).
Laser output power
(Not available for QSFP+ transceivers)
Displays the laser temperature, in Celsius and Fahrenheit.Laser temperature
(Not available for SFP, SFP+, XFP, and QSFP+ transceivers)
Displays the temperature, in Celsius and Fahrenheit.Module temperature
Displays the voltage, in Volts.Module voltage
(Not available for XFP transceivers)
Displays the laser received optical power, in milliwatts (mW)
and decibels referred to 1.0 mW (dBm).
Laser rx power
(Not available for SFP, SFP+, QSFP+, and CFP transceivers)
Displays the receiver signal average optical power, in milliwatts
(mW) and decibels referred to 1.0 mW (dBm).

(Not available for XFP, QSFP+, and CFP transceivers)
Displays whether the laser bias power setting high alarm is On
or Off.
Laser bias current high alarm
Displays whether the laser bias power setting low alarm is On
or Off.
Laser bias current low alarm
Displays whether the laser bias power setting high warning is
On or Off.
