System Wavelength Setting

The operational wavelength range of the MX10C and MX40C series extends from 1250 nm to 1610 nm. The three calibration
wavelengths of the power monitors, 1310 nm, 1550 nm, and 1590 nm, represent the centers of the O-band, C-band, and L-band
and provide the user with accurate power readings at or near those wavelengths.
The system wavelength should always be set to the wavelength closest to that of the laser source coupled to the Laser In
bulkhead. The instrument's system wavelength is factory-preset to correspond to the wavelength band of the integrated laser
source. If an external laser is to be used with the instrument, the system wavelength may need to be changed. This function
exists in the Utility Menu.
From the Home screen, tap the MENU button to bring up the Utility Menu as shown.
Then tap the System Wavelength bar as shown below to bring up the three wavelength choices. Tap the desired wavelength to
set the System Wavelength.
