Line Description
TX Power Low
Warning threshold
Factory-defined setting. Value can differ between SFP and SFP+.
Power Low Warning
threshold
Factory-defined setting. Value can differ between SFP and SFP+.
Temperature Current temperature of the sfps. If this temperature crosses Temp
High alarm/warning thresholds, the temperature high alarm/warning
flag is set to true.
Voltage Current voltage of the sfps. If this voltage crosses voltage high
alarm/warning thresholds, the voltage high alarm/warning flag is set
to true.
Tx Bias Current Present Tx bias current of the SFP. If this crosses bias high alarm/
warning thresholds, the tx bias high alarm/warning flag is set to true.
If it falls below the low alarm/warning thresholds, the tx bias low
alarm/warning flag 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 flag is set to true. If it
falls below the low alarm/warning thresholds, the Tx power low
alarm/ warning flag is set to true.
Rx Power Present 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 flag is set to true. If it falls below the low
alarm/warning thresholds, the Rx power low alarm/warning flag is
set to true.
Data Ready state
Bar
This field 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 flag is set to true.
Temperature High
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.
