Auto
λ
feature
When in one of the Auto
λ
modes, the OLTS-85 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.
Auto-
λ
-Multi mode is a proprietary Viavi solution that reduces
testing time to a minimum by simultaneously testing at all
wavelengths (see Fig. 20 ). Combined with a compatible power
meter (e.g. OLP-85), the power meter automatically sets itself up
for Multi
λ
test.
Auto-
λ
-Multi should be selected every time the optical
powermeter supports the Auto-
λ
-Multi feature.
