WA-7000 Multi-line Wavemeter Optical Channel Analyzer


Now in final refurbishment stage and coming soon, two EXFO WA-7600 wavemeters with single frequency lasers for highest accuracy.

The WA-7000 Multi-line Wavemeter combines Burleigh’s proven scanning Michelson interferometer-based technology with advanced digital processing. The result is the ability to measure and differentiate the absolute wavelengths of up to 200 discrete optical signals. The accuracy of these measurements is ± 1.5 pm. What’s more, the WA-7000 can simultaneously measure the individual powers of the discrete optical signals.

Unlike other multi-wavelength meters, the WA-7000 provides the full optical spectrum for the most precise WDM channel analysis. Its spectral resolution of 50 pm results in a narrow, sharp-edged spectral response, so discrimination between closely spaced WDM channels is easily achieved.

The WA-7000 Multi-line Wavemeter automatically processes measurement data to provide various information that is critical to WDM system performance. In addition to resolving the individual optical carriers and accurately confirming their wavelengths and powers, the WA-7000 calculates parameters such as channel spacing, drift, and signal-to-noise ratios for the most complete WDM channel analysis.
