Measuring Power or Loss (FPM-600 and FOT-600)
Power Meter/Light Source/Optical Loss Test Set 29
Automatically Detecting Wavelength
Automatically Detecting Wavelength
Compatible sources (such as FOT-600 and 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 (FOT-600
and FLS-600: see Modulating the Source
Signal on page 34) 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.
