GLOBAL INVACOM UNIVERSAL FIBRE OPTICAL OUTPUT LNB
 
Part 925004
 
Features
 
- Converts all 4 universal IF bands to a single optical output (H/H - H/L - V/H - V/L = single optical output).
- Capable of supplying all converted signals to 32 distribution points spread over a 10 kilometre radius.
- 40 mm Feed Horn.
 
The GI FibreMDU Optical Output LNB radically changes how satellite IF signals are dealt with compared with conventional universal LNBs. This innovative new design uses patented technology to frequency stack both horizontal and vertical polarities, creating a single IF frequency range of 950MHz - 5,45GHz. The newly created single band is then frequency modulated optically and output using a 1310nm laser internal to the Optical Output LNB.
 
Powered separately the Optical LNB takes the required <450mA from a standard 12V supply utilising a standard female F type connector. Fibre connection is made via a standard FC/PC connector feeding the distribution network on single mode fibre optic cable. With an optical output +7dBm the GI FibreMDU Optical Output LNB is easily capable of driving up to 32 GI FibreMDU converters located within a 10km radius.
