Installation
The connections must feature a high-quality polish. The reference bre may be
used for no more than 500 reference measurements. Then the connections have
to be polished again. Please treat the reference bres with great care. After 2,000
reference measurements, the reference bres should be replaced. Please also
note the details provided by the manufacturer.
Only special reference bres may be used to connect the section
requiring testing.
The measurement must be taken with the operating wavelength
used later on and with the transmitter belonging to the
measurement receiver. The transmitter, receiver and bre type
should be coordinated.
The limit values stated for the maximum permitted end-to-end
link attenuation already contain an attenuation reserve. Do
however take into account possible measurement inaccuracies
and the tolerance of your measuring device. These should be
included in the limit value for the maximum permitted end-to-
end link attenuation.
Note in particular that the comparably high attenuation of POF
coupled with several plug-in connectors reduces the maximum
length of the bre-optic connection.
