Line Description
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.
