ELECTING AN OUTPUT PORT AND WAVELENGTH
Selecting an output port and wavelength
1. To select output, tap SM or MM on top of the display.
– or –
Press the
[
A
]
key, tap [ Output Selection ] and tap the desired
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 –
Press the
[
A
]
key, tap [ Source Selection ] and tap the desired
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.
3. Press the
[
F
]
key.
4. To turn on the selected lasers, tap the [ Laser On/Off ] button
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-  .
