BFi Optilas has introduced a family of optical wavelength meters, designed for dense wavelength division multiplexing (DWDM) applications.
The 228 Series Optical Wavelength Meter performs wavelength characterisation of tunable DWDM lasers, DFB lasers, and VCSELs.
Two versions of the 228 Series Optical Wavelength Meter are available.
The model 228A is suitable for the most demanding applications, measuring wavelength to an accuracy of about +/- 0.3 pm over the range of 700 to 1650 nm.
For less exacting test requirements, the model 228B is a lower-price alternative with an accuracy of about +/- 1.0 pm.
The accuracy of the 228 system is maintained over long periods of time by calibrating continuously with a built-in wavelength standard, and its measurement repeatability supports a confidence level of 3-sigma (> 99.6 per cent).
