Nearfiled Analyzer
The Nearfiled (NF) describes the optical power density on the surface of a radiating source or the end of a fiber. The near field measurement can determine the refractive index profile of multimode fibers and the fiber's mode filling.
With the included application OPL_LCA the Encircled Flux measurement is calculated and analyzed against the appropriate IEC template.
