Coherence analysis of ±165 mm

Because the Q8347 uses a Michelson interferometer, the system is capable of performing coherence analysis.

This feature makes it easy to evaluate the noise rejection performance of a disc LD. In addition,

the travel of the interferometer can be greatly increased to allow analysis over a range of ±165 mm.

As a result, more detailed analysis can be performed in addition to the conventional secondary maximum peak (α value).

Curve fitting function

The Q8347 offers sech2 and Gaussian function curve fitting. Therefore, it can be used for spectral analysis of soliton transmission systems.

List display

The peaks of spectrum or coherence data can be displayed as digital data containing up to 200 points.

The separation and level of each channel of an optical WDM transmission system can be seen at a glance.

Displayable optical frequency

In addition to the normal wavelength display mode, the measurement spectrum can also display the optical frequency.

Since light in terahertz units can be read directly, this is useful for measuring optical wavelength

division multiplexing and chirping from LDs, as well as for analyzing Soliton transmission systems.
