Measured Laser Temperature or Wavelength. For DWDM applications, the diagnostic interface report either laser wavelength or temperature, with a given module�s reporting defined by bit 1 of the object sfpConfigOptionalWdm. The reported TEC current is defined as a positive number for cooling and a negative number for heating starting at -3276.8. The increments are of 0.1 steps yielding a total range of -3276.8 to +3276.7, The accuracy of the TEC current monitor is vendor specific but must be better than �15% of the maximum TEC current as stored in the TEC Current High Alarm Threshold
