Optical Satellite Receiver I.R.I.S. GI-FIBRE-IRS-GTU/MKIII Quatro — quattro LNB for fibre distribution

The I.R.I.S. GI-FIBRE-IRS-GTU/MKIII Quatro is an optical satellite receiver module designed for fibre-based distribution of satellite TV signals. Provided in a quattro LNB configuration, it delivers four separate outputs corresponding to the standard satellite polarisation and band combinations (vertical low, vertical high, horizontal low, horizontal high) and converts RF signals for transmission over an optical link to a headend or distribution node. The unit is intended for installations where reliable, low-loss signal distribution over long distances is required, for example multi-dwelling buildings, commercial headends and cable network feed points.

Advantages

The quattro LNB configuration provides four dedicated outputs to support multiple tuners or receivers without signal switching, enabling simultaneous access to each polarisation and band. Optical conversion reduces RF losses and interference on long cable runs and supports centralised management of satellite feeds in headend environments. The compact optical module design simplifies integration into fibre distribution systems and minimises the need for multiple separate LNBs at the dish.

Suitable for

• Headend installations and central distribution of satellite channels
• Multi-dwelling units and apartment buildings requiring multi-receiver distribution
• Cable network nodes and fibre-to-building satellite feeds
• Professional installations where low-loss long-distance transmission is needed

Key specifications

• Quattro LNB configuration with four distinct outputs for vertical/horizontal low/high bands
• Optical conversion for RF-to-fibre transmission
• Designed for headend and fibre distribution systems
• Compact module form factor suitable for dish-mounted optical heads
• Compatibility with standard satellite reception frequency bands and polarisation switching at the headend

How to use

Mount the optical module in the appropriate position on the satellite dish assembly and connect the coaxial feed points to the quatro output terminals as specified by the installer. Connect the optical output to the fibre link leading to the headend or distribution node using an appropriate optical connector and fibre type. At the receiving end, use an optical receiver or fibre-to-RF converter compatible with the module to restore the four RF outputs for distribution to tuners or multiswitches. Follow local regulations and industry best practices for grounding and lightning protection during installation.

Usage recommendations

Use the module as part of a professionally designed fibre distribution system; verify optical power budgets and headend receiver compatibility before commissioning. Regularly inspect mechanical mounts and optical connections and maintain proper grounding and surge protection to ensure long-term stable operation.
