● Fresnel Reflection

The far-end Fresnel reflection can be measured for four

wavelengths (1310/1450/1550/1625 nm).

● Group Delay Characteristics

The fitting formula supports cubic or quintic Sellmeier, and

polynomials can be applied to various types of fibers.

● Chromatic Dispersion Characteristics

The zero and total dispersion can be displayed along with the

delay, dispersion and dispersion slope at 0.1 nm steps.

The MW9076D1 has a built-in function for measuring chromatic dispersion even outdoors. The chromatic dispersion can be 

measured automatically over a wide range from 1300 to 1660 nm from one end of the fiber. The dispersion reproducibility is 

±0.05 ps/(nm

and the dynamic range is 30 dB.

The MW9076D1 can be operated from an external PC using remote commands to measure the chromatic dispersion.

For detail of the chromatic dispersion measurement, refer to the document of “Product introduction MW9076 series Optical Time
