EXFO is pleased to announce the introduction of the new solution in the family of Optical Spectrum Analyzers, the FTBx-5243-HWA. HWA stands for high wavelength accuracy. This EXFO’s solution is a game changer. Delivering a best-in-class wavelength uncertainty of ±10 pm in the C-band, it replaces both a regular OSA and an entry-level wavelength meter. Being able to perform all the required spectral tests using a single device brings about significant savings in capital expenditures and faster testing time.
