The output power coupled into plastic fiber is measured with a large area detector after a short fiber (about
30 cm). This value must not used for calculating the power budget for a fiber optic system with a long fiber
because the numerical aperture of plastics fibers is decreasing on the first meters. Therefore the fiber seems
to have compared with the specified value a higher attenuation on the first meters.
