The Exfo FTB-5230 is a powerful optical spectrum analyzer (OSA) designed to meet the challenges of DWDM applications. With the increasing sophistication of communication networks comes the need for equally powerful test and measurement equipment designed to meet the challenges of DWDM. Whether testing involves manufacturing, installing and commissioning network fiber, or managing, maintaining, monitoring and troubleshooting performance elements, EXFO’s FTB-5230 Optical Spectrum Analyzers (OSAs) are ready to handle any situation. Since CWDM systems generally use uncooled lasers, whose typical wavelength drift is 0.1 nm per degree Celsius, it is critical to track the evolution and drift of the lasers’ central wavelength. And since path attenuation can significantly vary within a single channel, passband drift also creates power drift. This is why it becomes extremely important to monitor—simultaneously for all CWDM channels—the evolution of peak power and wavelength over time. The FTB-5230 Optical Spectrum Analyzer’s Drift mode functionalities makes this an easy task. Specifications. Wavelength range (nm): 1250 to 1650. Resolution bandwidth FWHM (nm): <= 0.1.
