Notes:
1. The output power coupled into plastic fiber P
2. The electrical input signal fulfills t
which is ideally coupled to the Sidelooker. 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.
Due to the direct coupling of the fiber to the LED at the end of the short fiber UMD (uniform mode distribution) will be observed. Therefore the
following section of the cable has higher losses compared with EMD (equilibrium mode distribution)
