Measuring Power or Loss (FPM-600)
Automatically Detecting Wavelength
Automatically Detecting Wavelength
Compatible sources (such as FLS-600) can transmit their wavelength value
through the fiber, avoiding the need to manually match the source and
power meter wavelengths.
Note:
When you receive an auto-wavelength signal or when the source is in auto-
switching mode, you cannot manually change the power meter
wavelength. The power meter behavior is totally determined by the source.
To receive the auto-wavelength signal or detect the source's
auto-switching mode:
1. Connect a compatible source to your power
meter.
2. Activate the source in Auto mode (FLS-600:

Modulating the Source Signal

or in auto-switching mode.
Your power meter automatically matches the source wavelength. If the
wavelengths differ, it also beeps and returns you to normal operating
mode.
