IM AQ7280-01EN
Setting the Wavelength and the Modulation Mode
The following measurement light wavelengths can be generated.
You can produce continuous light (CW) or light that has been modulated at the selected frequency
(modulation mode).

1 Not applicable for 1383 nm for AQ7283J.
2 Supported on firmware version 2.01 and later.
Note
• Connect an optical fiber cable to the OTDR port of an OTDR unit with the /SLS option.
• The AQ7283E’s 1625 nm and the AQ7283F’s 1650 nm measurement lights are emitted from OTDR port 2.
Other measurement lights are emitted from OTDR port 1.
• Turn the light source on after you set the wavelength and the modulation mode.
• You can also start the light source feature from the OTDR display screen. For the procedure, see section
2.10.
Outputting Visible Light (VLS module)
1.
From the top menu, select
VLS
to display the following screen.
Turns the light on
The measurement light turns on.
A mark appears on the AQ7280 display
to indicate that the light is on.
Turns the light off
The light turns off. The light mark
disappears.
Emission wavelength
Set the modulation mode
(CW, 2Hz).
Note
• Connect an optical fiber cable to the optical output port of a VLS module or OPM module (with a visible
light source).
• You can also start the visible light source feature from the OTDR display screen. For the procedure, see
section 2.10.
