Line Description
Power Low Warning
threshold
Factory-dened setting. Value can dier between SFP and SFP+.
Temperature Current temperature of the SFPs. If this temperature crosses Temp High alarm/
warning thresholds, the temperature high alarm/warning ag is set to true.
Voltage Current voltage of the SFPs. If this voltage crosses voltage high alarm/warning
thresholds, the voltage high alarm/warning ag is set to true.
Tx Bias Current Present transmission (Tx) bias current of the SFP. If this crosses bias high alarm/
warning thresholds, the TX bias high alarm/warning ag is set to true. If it falls
below the low alarm/warning thresholds, the TX bias low alarm/warning ag is set
to true.
Tx Power Present Tx power of the SFP. If this crosses Tx power alarm/warning thresholds,
the Tx power high alarm/warning ag is set to true. If it falls below the low alarm/
warning thresholds, the Tx power low alarm/ warning ag is set to true.
Rx Power Present receiving (Rx) power of the SFP. This value is either average Rx power or
OMA. This depends on the Rx Power measurement type displayed above. If this
crosses Rx power alarm/warning thresholds, the Rx power high alarm/warning ag
is set to true. If it falls below the low alarm/warning thresholds, the Rx power low
alarm/warning ag is set to true.
Data Ready state
Bar
This eld indicates that the transceiver has achieved power up and data is ready.
This is set to true if data is ready to be sent and set to false if data is being
transmitted.
Rx LOS state This is the digital state of the Rx_LOS output pin. This is set to true if the operating
status is down.
Tx Fault state This is the digital state of the Tx Fault output pin.
Rate Select state This is the digital state of the SFP rate_select input pin.
RS state This is the reserved digital state of the pin AS(1) per SFF-8079 and RS(1) per
SFF-8431.
Tx Disable state If the admin status of the port is down then this ag is set to true.

Alarm Flag
This can be either true or false, depending on the Current voltage value displayed
above.
Voltage High Alarm
Flag
This can be either true or false, depending on the Current Temperature value
displayed above.
Tx Bias High Alarm
Flag
This can be either true or false, depending on the present Tx bias current value
displayed above.
Tx Power High
Alarm Flag
This can be either true or false, depending on the Current Tx bias power value
displayed above.
Rx Power High
Alarm Flag
This can be either true or false, depending on the Current Rx power value displayed
above.
Temperature Low
Alarm Flag
This can be either true or false, depending on the Current Temperature value
displayed above.
Voltage Low Alarm
Flag
This can be either true or false, depending on the Current voltage value displayed
above.
