The Yokogawa AQ6151B Optical Wavelength Meter is an ideal instrument for accurately measuring the optical wavelength of optical devices and systems with wavelength ranges from 900 nm to 1700 nm. By employing a Michelson interferometer and a high speed Fast Fourier Transform (FFT) algorithm, the AQ6151B can measure not only a single wavelength laser signal, but also a multiple wavelength laser signal from a DWDM system and Fabry-Perot laser.

Key Features:

1. High wavelength accuracy: ±0.2 ppm

2. Wavelength range (3 types): 900-1700nm, 1200-1700nm, 1270-1650nm

3. Measurement time of 0.2 seconds or less

4. Up to 1024 wavelengths can be measured at once

5. Single wavelength type and multi wavelength type

6. Support modulated light and filter measurement
