Selecting an output port and wavelength

1. To select output, tap SM or MM on top of the display.
– or –
[A]
Press the key, tap [Output
output.
The menu is closed and the measurement display is shown.
2. To select a wavelength, tap the desired wavelength(s) on the
measurement display.
– or –
[A]
Press the key, tap [Source
wavelength(s).
If Auto-  is not selected, only one wavelength can be selected.
To select Auto- see "Selecting a modulation or Auto- mode"
on page 54.

4. To turn on the selected lasers, tap the [Laser
or press the central key.
About Auto- mode
When in one of the Auto- modes, the OLT-85/OLT-85P embeds
wavelength ID information into the emitted signal(s). This
wavelength ID information can be utilized by a compatible Viavi
power meter (e.g. OLP-85) for automatic wavelength setup and
for simultaneous reception of multiple wavelengths.
The OLT-85/OLT-85P provides two Auto- modes:
• Multi-: Multi- is a proprietary Viavi solution that reduces
testing time to a minimum by simultaneously testing at both
wavelengths. When activated both wavelength are measured
and displayed simultaneously.
Auto--Multi should be selected every time the optical
powermeter supports the Auto--Multi feature.
• Serial- automatically toggles between the selected
wavelengths. Combined with a compatible power meter (e.g.
OLP-3x, OLP-85), the power meter automatically sets up with
correct wavelength settings.
Serial- should be selected when low levels are expected on
the optical power meter or when the power meter doesn't
support Multi-.
