High signal gain
Very good carrier-to-noise ratio
Solid design and workmanship
Actual performance better than parameter
specification
All components available from the same manu-
facturer
FibreIRS LNBm is larger and heavier than a
classical LNB – select a dish with a robust LNB
holder
Expert Opinion
but this is not a problem as
the 80-90 dBµV we achieved
in our test setup was a very
strong signal. Normally, you
have 60-70 dBµV or so.
So, we can do nothing
but heartily recommend the
optical system of GlobalIn-
vacom for large distribution
systems. You can forget
about signal attenuation or
carrier to noise ratio. Using
optical components, practi-
cally everybody can build
a large distribution system
without tedious gain mar-
gin calculations or interfer-
ence concerns. No more
problems. The battle is over
thanks to fibre optics.
