AXING SPECTRA – Single-Fiber SAT-IF & GPON Solution

One fiber. Two services. Every building.

AXING SPECTRA combines SAT-IF distribution with GPON on a single fiber infrastructure — cutting cabling, hardware and installation effort for MDU, hospitality and campus projects.

AXING’s SAT & GPON solution enables the delivery of satellite TV and IP-based services over a single fiber network.
Instead of deploying separate infrastructures for RF and IP services, both signals are efficiently combined and transported — reducing installation complexity, material costs, and long-term operational effort.
The solution is designed for projects where scalability, long-distance transmission, and infrastructure efficiency are key requirements.

Benefits at a Glance:

Reduced Infrastructure Complexity
Combine satellite TV and IP services within one fiber network — minimizing cabling, installation time and integration effort.
Optimized Cost Structure
Lower CAPEX through shared infrastructure and reduced hardware requirements, while maintaining high performance.
Long-Distance Transmission
Reliable signal transport over distances up to 50 km — ideal for campus networks, resorts and distributed buildings.
Scalable Architecture
Easily expand the system to support additional users, buildings or services without redesigning the network.
Future-Ready Network Design
Supports the transition towards fully IP-based services while maintaining compatibility with existing TV systems.

How It Works

Satellite signals are processed centrally
AXING satellite gateway selects and prepares transponders within a single L-band for efficient transport over optical infrastructure.
RF signals are converted into optical transmission
The optical transmitter converts the RF signal into a 1550 nm optical signal for long-distance fiber transport.
SAT and GPON are combined on a single fiber
Both satellite TV and IP data are transmitted over the same fiber infrastructure using wavelength multiplexing.
Signals are received and distributed at the building level
At the building or home entry, an optical receiver converts the optical SAT signal back into RF, providing a direct RF output for connection to standard TVs or set-top boxes.
In parallel, the GPON signal remains available and can be passively distributed further to individual units for IP-based services.

System Architecture & Distribution Chain

Deliver satellite TV and IP services over a unified fiber infrastructure — from central signal processing to building-level distribution.

Satellite Gateway – Processes up to 32 transponders from two satellite positions (4+4 inputs) into a single SAT/IF band optimized for fiber transport.
Optical Satellite Transmitter (OTXS) – Converts RF to 1550 nm optical signal. Reliable transport up to 50 km without intermediate amplification.
Optical Amplifier (EDFA) – Amplifies SAT signals to 20 dBm to overcome high split ratios and long distances
Optical Multiplexer / Demultiplexer (OMX) – Combines SAT and GPON wavelengths on the outbound fiber, separates them on the inbound side. Passive, no power required.
Optical Line Terminal (OLT) – Manages GPON traffic between the core network and connected ONUs. Standard GPON protocol, interoperable with common ONU models.
Optical Splitters assive signal distribution to multiple units. No power, no active components in the distribution path.
Optical Receiver (ORX) Recovers the RF signal at the building or home. Direct RF output to TVs or STBs; GPON continues on to the IP side for broadband services.

Single Fiber, Two Services: The entire chain is designed so that one physical fiber carries both services end-to-end. No hybrid cabling, no parallel runs.
