Global Invacom - Optical TV - LNB to include Optical Transmitter, Global F925004
Item Code: F925004
Brand: Global Invacom
Manufacturer: Global Invacom
Description
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.
The 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 passive distribution network on single mode fibre optic cable.
With an optical output of +/- 6.5 dBm the GI FibreMDU Optical Output LNB is easily capable of driving up to 32 GI FibreMDU converters (see GI FibreMDU specification sheet) located within a 10km radius.
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 distributed points spread over a 10 kilometer radius
- 40mm Feed Horne for an offset Dish
