Automated testing of DFBs, Fabry-Perot lasers and passive components, as well as trace comparison Broad detection range: 950 to 1650 nm Power range: +18 to -75 dBm Wavelength uncertainty of ± 15 pm within the C and L bands Cost-effective wavelength calibration with the CKT-01 HCN Wavelength Reference Cell To achieve maximum efficiency in your manufacturing environment, EXFO created the IQS-5250B* Optical Spectrum Analyzer (OSA). This next-generation OSA delivers true spectral distribution of CW and modulated signals. Measurement of signal-to-noise ratio (SNR) and sidemode depth profile can now be performed accurately, even when characterizing very closely spaced peaks. This innovative OSA design meets all testing requirements for systems and components with 50 GHz spacing. The IQS-5250B* OSA is an efficient three-slot module for the IQS-500 Intelligent Test System, only from EXFO.
