A new optical transport system will push radio signals over fibre optic cables for far longer distances than currently possible, using novel amplification methods. Radio over Fibre technology converts wireless signals into light pulses that travel through optical fibres, combining the reach of fibre networks with the flexibility of radio transmission. The problem is that these signals degrade over long distances, requiring frequent amplification that adds cost and complexity. This project develops a new approach to amplification that extends the usable transmission range, making the system practical for longer routes. If successful, this could improve the infrastructure that carries mobile phone signals, broadcast television, and wireless data between transmission towers and central hubs. The technology underpins how signals travel from a roadside mast to the core network—a step most people never see, but one that determines whether a video call drops or a live broadcast reaches its destination. Longer reach means fewer intermediate amplifiers, lower power consumption, and simpler network design. This is an applied engineering project with a clear commercial goal: a working prototype for extended-distance Radio over Fibre transmission. The immediate impact is on network operators and equipment manufacturers, not end users directly—but the result would be more reliable wireless connectivity over greater geographic spans.
