High-speed measurement

Measurement time Approx. 6.7 ms (per measurement point) Approx. 4 seconds (within the specified span)

The interval between scans (measurement time) is approx. 4 seconds.

This means that the Q7750 can complete a measurement in 4 seconds,

whereas the previous measurement process took several tens of seconds.

If the measurement time is too long, accurate results may not be obtained because

the characteristics of the device under test may change due to environmental conditions such as

temperature.

The Q7750 completes measurements in a short period of time, ensuring high-speed,

accurate measurements that are unaffected by the temperature characteristics of the device under test.

The Q7750 has a maximum optical frequency resolution of 50 MHz,

which enables measurements in the field of ultra-high-resolution optical carrier frequencies that were not

previously possible.

Amplitude and chromatic dispersion characteristics of optical devices

for DenseWDM or Ultra-Dense-WDM can be easily measured (channel steps: 100 GHz, 50 GHz, 25 GHz,

etc.).

Selectable wavelength spans from 70 nm (maximum) to approximately 0.1 nm (minimum).
