FibreIRS Duo Package: Optical Headend + Quattro GTU Multiswitch Integration

This professional-grade FibreIRS solution combines the flexibility of optical distribution with the reliability of traditional multiswitch systems, making it ideal for apartment blocks, hotels, and large residential installs.

🔧 System Overview

At the core of this setup is the Global Invacom OTx Kit 1310nm, a compact optical headend designed to convert both satellite and terrestrial RF signals into optical output for distribution over fibre.

The OTx replaces the need for separate optical LNBs and external transmitters, delivering a complete headend solution in one unit, supplied with a wideband LNB.

⚙️ How It Works with a Quattro GTU + Multiswitch

This system can be expanded beyond standard FibreIRS by integrating a Quattro GTU (Gateway Termination Unit) to feed a conventional multiswitch system:

Step-by-step signal flow:

1. Satellite + Terrestrial Reception
   • The included wideband LNB captures satellite signals.
   • Terrestrial signals (Saorview / DVB-T/T2) are combined at the headend.
2. Optical Conversion (OTx)
   • The OTx converts RF signals into a 1310nm optical signal, distributed via fibre cabling across the building.
3. Optical Distribution
   • Fibre runs replace traditional coax, enabling:
     • Longer distances
     • Minimal signal loss
     • Cleaner installation in large or complex buildings
4. Quattro GTU Conversion
   • At the distribution point, a Quattro GTU converts the optical signal back into:
     • Four satellite IF outputs (VL, VH, HL, HH)
     • Plus terrestrial RF
5. Multiswitch Integration
   • These outputs feed directly into a standard multiswitch system, allowing:
     • Distribution to multiple apartments or rooms
     • Compatibility with Sky™, Freesat, Saorview, and international satellite services
     • Expansion using cascade multiswitches

🧩 Why This Hybrid Approach Works

• Combines fibre backbone efficiency with familiar multiswitch architecture
• Ideal for retrofits where coax distribution already exists internally
• Allows centralised dish installation with distributed signal processing
• Supports large-scale MATV/SMATV systems
