The Exfo WA-7600 Optical Channel Analyzer is a high-performance benchtop instrument for absolute wavelength and power measurement in DWDM and ROADM systems. Using scanning Michelson interferometer-based Wavemeter technology, it simultaneously measures the wavelengths and individual powers of up to 256 optical signals with absolute uncertainty of ±0.2 ppm or ±0.3 pm. The analyzer automatically calculates OSNR and channel spacing while graphing wavelength and power trends over time.
