Line Description
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 transmission (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 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 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.
Tx Power High
Alarm Flag
This can be either true or false, depending on the Current Tx
bias power value displayed above.
