Digital Diagnostic Monitor TX_FAULT Alarm/Warning Interrupt on page 37 for additional information on transceiver Digital Diag-
nostic Monitoring status.
bit will be set low after each first successful sampling occurs and remain low until the transceiver looses power or a failure occurs.
The bit must be set low within 1 second of reaching a valid stable power supply level.
lyze the status of the transceiver as an alternative to decoding the real-time values in bytes 96-105. Alarm flags indicate levels that
are likely to be associated with link failures. Warning flags indicate levels that are outside of normal levels, but not necessarily
cause for immediate concern (could be used for end-of-life indicators).

State of TX Disable input pin
Read/Write bit that allows software disable of laser. Writing a ‘1’ disables
the laser. Default power value is ‘0’. This bit is internally OR’ed with the
hard TX_DISABLE pin value.
Digital state of AS1 input pin.
Digital state of rate_select input pin.
Not Applicable
State of TX Fault output pin.
Sate of LOS output pin.
Indicates transceiver has achieved power and Digital Diagnostic data is
ready to be read.
Not Applicable
For soft application_select, a 6-bit binary number (TS) that represents the
sequence of the Application code in the AST. It is written by the host for
select module behavior.
Set when internal temperature exceeds the bytes 0-1 level.
Set when internal temperature is below the bytes 2-3 level.
Set when TX VDD exceeds the bytes 8-9 level.
Set when TX VDD is below the bytes 10-11 level.
Set when Laser Diode Current exceeds the bytes 16-17 level.
