Characterizing Chromatic Dispersion in the Field

Chromatic dispersion (CD) causes pulse broadening and can have a very negative impact on transmission performance by increasing the Bit Error Rate. EXFO’s FTB-5800 CD Analyzer offers high performance in a field-ready unit for all chromatic dispersion testing situations.
