Note 1
: The output power coupled into plastic fiber P
opt
is measured with a large area detector at the
end of a short length of a fiber (about 30 cm), 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).
Note 2
: The electrical input signal fulfills t
PWV(min)
= 22.9 ns and t
PWV(max)
= 24.1 ns. For further details
see page 3.
