Return firmware revision in the form Major/Minor
Function
Set or read laser disable state
Set or read laser disable state at power up.
00h causes the module to power up in a laser
disabled state.
Fine tune the current wavelength
Returns the wavelength of the current channel
in pm.
Returns the laser bias current in mA.
Returns the current submount temperature in
C*10 (e.g. 125 would be 12.5 C)
Returns the BFM current on the short wavelength
side of the Etalon. Result is in uA.
Returns the BFM current on the long wavelength
side of the Etalon. Result is in uA.
Return status byte.
Returns the serial number of the module.
Returns laser threshold calibration for
the current channel
Returns laser modulation calibration for
the current channel
Returns laser bias calibration for
the current channel
Returns laser wavelength calibration for
the current channel
Returns laser type :
1= Single BFM
2= Dual BFM/Etalon
Return submount temperature calibration for
the current channel
Returns the number of optical channels the
module supports (1 to 4)
e.g. first byte = 1, second byte = 2 would
be revision 1.2)
Returns transmitted optical power in uW
