QM Optical Fibre LNB

This QM optical Fibre LNB converts the satellite signal to optical signals. Each SAT level is stacked one by one and converted to the frequency range of 950 MHz - 5.45 GHz.

The new created frequency bands are then transmitted through an optical wavelength of 1,310 nm.

The power of the LNB is 10 mW and therefore has a higher output than, for example, the comparable versions by Global Invacom and/or Polytron.

The optical signal distribution is only done by a single-mode fibre cable.

The LNB is powered via a coaxial cable and the external (included) 12 V power supply that is equipped with an F-connector.
