Dual Mode Indicator
The word “Dual” is shown when two
wavelengths are being transmitted
simultaneously.
The Main screen of the DLS 655 acts as the general user interface for fiber testing.
Up to two wavelengths may be transmitted on a single output port at the same time.
When a single wavelength is selected for transmission, only that wavelength will be shown onscreen.
Both wavelengths will be shown onscreen only when they are both selected for transmission.
