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