Enabling Auto λ mode
Auto λ is a special feature developed by JDSU that allows you to
identify wavelengths automatically. To do this, the signal is
modulated at a certain frequency (by a light source equipped
with Auto λ, such as a JDSU OLS-85), which can be detected by
a JDSU .
OLP-85
In Auto λ mode the detected wavelength will be included in the
λ table. As long as the detected wavelength is active, it cannot be
deleted from the λ table.
Wavelengths cannot be reliably detected if:
• the receive level is too low,
• wavelength encoding cannot be detected due to interference
• you are measuring the absolute level of a system that does not
have wavelength encoding matching JDSU power sources.
