The older versions of the AQ6370 (AQ6370B and AQ6370D-10) show the trace while optical alignment is being performed. However, the newer version, AQ6370D-12, does not show a trace while the optical alignment is being performed. This should not be a cause for concern as long as the device shows the alignment has been completed successfully.
High performance with a 20 picometer wavelength resolution supporting 25 GHz DWDM spacing and 40G/100G applications, this OSA also supports non-Telecom applications with a wavelength range from 600nm to 1700nm.
Measures the power intensity of light across different wavelengths in the electromagnetic spectrum.
