The Exfo FTB-5240B 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-5240B Optical Spectrum Analyzers (OSAs) are ready to handle any situation. In addition, the FTB-5240B OSA gives you the best of two worlds: the impressive specifications of a lab-quality instrument in a state-of-the-art, field-ready modular unit for fast, accurate and efficient fiber characterization. This application note presents in-band OSNR measuring techniques become essential to accurately measure the OSNR in reconfigurable networks. Specifications. Wavelength range (nm): 1250 to 1650.
