Auto-
λ
-Serial automatically toggles between all selected
wavelengths (see
Fig. 17
), and combined with a compatible
power meter (e.g. OLP-3x, OLP-85) the power meter
automatically sets up with correct wavelength settings. This
mode should be selected when low levels are expected on the
optical power meter or when the power meter doesn't support
Auto-
λ
-Multi.
Auto-
λ
-Serial should only be used in special cases, for instance
when there is very low optical level on the optical power meter
or when the optical power meter only supports Auto-
λ
-Serial.

Notes:
Wavelengths cannot be reliably detected by a power
meter,
• if the receive level is too low,
• the wavelength encoding cannot be detected due to
interference,
• or if you are measuring the absolute level of a system
that does not have wavelength encoding matching Viavi
power sources.
