The Exfo FLS-210A is a variable light source engineered for multiwavelength fiber optic testing in R&D and manufacturing environments. It delivers adjustable optical power across selectable wavelengths to support insertion loss and continuity measurements on passive components and optical links. The unit combines field portability with lab-grade performance through multiple power configurations, precise output control, and integration with EXFO’s FasTesT automated testing platform.
