NOTICE Wavelength Power Meter for CWDM-Demux (WPM-19) is designed to measure both wavelength and optical power of 19 wavelength optical signals in CWDM-Demux side.
Because users don’t need to use so expensive CWDM power meter to measure demux side.
WPM-19 is Automatic Wavelength Detection type.
By using this function of automatic wavelength detection, users can direct measure the wavelength and power of optical signal without setting up wavelength.
