SER (09h)
Return the module serial number. The serial number is 9 characters long and will typically
include upper-case letters A-Z, digits 0-9, a period “.” separator and may contain spaces
to pad the serial number to nine characters if needed. All characters are returned in ASCII
format. The serial number is sent in logical order i.e. first digit of the number is sent first.
Command is read-only
THR (0Ah)
Returns the laser threshold calibration. Calibration value is returned as an unsigned 16-bit value,
MSB first. This value is a factory set calibration value for internal control loop operation.
The value is specific to each optical channel that the module supports and the value will not
change under normal operation. Command is read-only.
MOD (0Bh)
Returns the laser modulation calibration. Calibration value is returned as an unsigned 16-bit
value, MSB first. This value is a factory set calibration value for internal control loop operation.
The value is specific to each optical channel that the module supports and the value will not
change under normal operation. Command is read-only.
BIS (0Ch)
Returns the laser bias calibration. Calibration value is returned as an unsigned 16-bit value,
MSB first. This value is a factory set calibration value for internal control loop operation.
The value is specific to each optical channel that the module supports and the value will not
change under normal operation. Command is read-only.
WAV (0Dh)
Returns the laser wavelength calibration. Calibration value is returned as an unsigned 16-bit
value, MSB first. This value is a factory set calibration value for internal control loop operation.
The value is specific to each optical channel that the module supports and the value will not
change under normal operation. Command is read-only.
THM (10h)
Returns the submount temperature calibration. Calibration value is returned as an unsigned 16-
bit value, MSB first. This value is a factory set calibration value for internal control loop
operation. The value is specific to each optical channel that the module supports and the value
will not change under normal operation. Command is read-only.
FWR (13h)
Returns the firmware revision. Result is returned as two unsigned bytes. The first value returned
is the major revision number, the second is the minor revision. Command is read-only.
POW (16h)
Returns transmitted optical power in uW. The reported power will only be accurate whilst
the module is wavelength locked (EIL flag active). During start-up and under certain fault
conditions this monitor may not return an accurate representation of the transmitted power.
Command is read-only.
