This modern device makes use of a patented technology to unite signals both of horizontal and vertical polarization into one signal at frequencies of 0.95 – 5.45 GHz. The resultant signal is subsequently modulated in an optical manner, for which purpose it comes to an internal 1310 nm transducer and further to the optical output.

The converter is fed through a separate input furnished with a connector of type F and consumes less than 450 мА from a standard 12 V power supply.

The optical connection is performed through a standard FC/PC connector.

Having the output power of +7 dB, LNB with its optical output GI FibreMDU is easily feeding up to 32 GI FibreMDU converters (see Specification) located within a radius of 10 km.

  • Converts 4 universal IF bands into one optical output;
  • Adds all converted signals to  32 consumer's points  located randomly  a distance of up to 10 km;
  • A standard 40mm feed.
