The Optical LNB is a high quality, high performance universal LNB. In addition to excellent LNB performance it provides a 1310 nm wideband optical output where all four satellite polarities are stacked into one frequency range (950-5450 MHz).
The Global Invacom Fibre Optic LNB has a single optical output which converts signals from 1 satellite to an optical signal. The LNB has a standard 40mm feed horn for mounting on a standard 80cm offset satellite dish.
The output of the LNB can be distributed, using single mode fibre optic cable, through a Passive Optical Network (PON) of up to 32 points (over short or long distances).
At each of the potential 32 points the Fibre Optic LNB is distributed to, the fibre can be connected to a Global Invacom Virtual Twin, Virtual Quad or Virtual Quattro for conversion back to IF (coaxial cable).
The Global Invacom Fibre LNB also has a standard F connector output which is used to provide power to the LNB via coaxial cable connected to a DC Inserter (DSI) and Power Supply (PSU) both are supplied with the Fibre Optic LNB.
Global Invacom?s FibreMDU range enables up to 32 homes, multiswitchs or combination of both to receive all digital signals from one satellite via a single 3mm fibre optic cable.
Key benefits of the Fibre MDU System include:
Reduced installation time and complexity.
No earth bonding required.
Long cable runs (kilometers) are no problem using standard FibreMDU equipment.
No slope compensation required.
Use a single 3mm armoured fibre optic cable (GI-3.0) instead of four coaxial for trunk cable runs.
Single fibre connection into the home to feedup to four digital satellite STB tuners.
