AQ6151B Optical Wavelength Meter
The AQ6151B is a high-accuracy optical wavelength meter for absolute wavelength measurement of lasers, optical transceivers and WDM systems from 900 nm to 1700 nm.
A Michelson interferometer with high-speed FFT processing measures single- and multi-wavelength signals, including DWDM and modulated transceiver outputs, with ±0.2 ppm accuracy and measurement times of 0.2 s or less.
Key Features
- High wavelength accuracy ±0.2 ppm (≈ ±0.3 pm at 1550 nm)
- Wavelength ranges: 1270–1650 nm, 1200–1700 nm, or 900–1700 nm
- Measure up to 1024 wavelengths simultaneously (multi-wavelength type)
- Measurement, analysis and PC transfer in ≤ 0.2 s
- CW and modulated light modes for transceiver and filter testing
- Built-in He-Ne reference laser, specified 30,000+ hours
- GP-IB and Ethernet remote control (SCPI)
