improves ambient light rejection in certain measurement setups.
Additionally, the modulated signals can be used for fiber
identification or for confirmation of continuity.
OLTS-85 instruments provide the Auto λ feature. When
activated, 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. This minimizes test time and prevents
common errors such as incorrect wavelength setting on the
optical power meter.
Furthermore, all OLTS-85 instruments provide Auto-λ-Multi and
Auto-λ-Serial modes, which significantly reduce test time
compared to manually switching wavelengths.
