Access the Menu page by tapping the blue Menu button on the Home page. The Menu page links to pages that allow the user
to control the system wavelength, display, sounds, and accent lights. Links to system information and guidance for obtaining
help form Thorlabs’ technical support are also included on this page. The functions and information available through this page
are described in the following sections.

4.8.1 System Wavelength
The path to access this screen: Home Page> Menu Page> System Wavelength.
The operational wavelength range of the MX40G and MX70G series of converters 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. Each converter's system
wavelength is factory-preset to correspond to the wavelength band of the integrated laser source. If an external laser is used
with the converter, the system wavelength may need to be changed as shown in Figure 40.
