The EXFO / Burleigh WA-1150 is a high-precision optical wavelength meter built around a scanning Michelson interferometer for absolute wavelength determination across the 700–1650 nm band. It simultaneously measures total optical power and maintains continuous calibration via an internal wavelength reference, delivering NIST-traceable results with 3σ confidence. The instrument characterizes DWDM components including DFB and tunable transmission lasers, calibrates passive optical components and test equipment, and supports demanding research and laser characterization workflows across CW, modulated, and SONET/SDH signal types.
