Broadcast Solutions

In the competitive broadcasting space, reliable delivery of high-quality audio and video is essential, especially during live events. RFOptic’s RFoF broadcast solutions are designed to meet the rigorous demands of TV broadcast companies and audio video applications for sports events, music concerts and theatrical productions. These solutions include fast auto-switch, doubly redundant RFoF links to ensure uninterrupted feed and reliable coverage of the event.

Why RFoF instead of coax for broadcast solutions?

Using RF over Fiber (RFoF) technology is preferred over coaxial cables due to its ability to extend the range of audio and video signals from sources such as microphones and cameras. In large outdoor event these distances can easily exceed several kilometers. Coaxial cables can become impractical for such distances due to high loss, weight and cost. RFoF solutions maintain signal integrity irrespective of such distances, reduce deployment and maintenance cost relative to high-quality, heavy and bulky coaxial cables.

Key characteristics for broadcast applications

RFOptic’s common broadcast solutions operate up to 6GHz and feature built-in low-noise amplifiers with a noise figure of approximately 5 dB, making them exceptionally suitable for sensitive audio applications. The transmitter (Tx) and receiver (Rx) units incorporate a 31.5 dB attenuator with 0.5 dB resolution, allowing for precise adjustment of signal levels ensuring consistent gain across RFoF links. These RFoF links operate over Single Mode Fibers to achieve long distance wideband coverage. In critical cases, dual links with 1:1 redundancy and auto-switch-on-failure provide for continuous and reliable feed.

Frequency range & RF coverage

These RFoF systems effectively cover various frequencies needed for broadcast applications, providing flexibility for diverse scenarios. The capability to maintain high-quality signals makes them ideal for broadcasting in challenging environments typical of outdoor events and large venues.

Broadcast applications & design

Broadcast RFoF solutions can be particularly valuable in scenarios such as motor racing, soccer, and large athletic events, where extensive coverage is essential. With RFoF technology, broadcasters can position microphones and cameras far from the main broadcast unit, capturing critical audio-visual from numerous remote locations and angles without signal degradation.

System configuration (example)

The system includes a compact RFoF transmitter and receiver linked by single-mode fiber extends operational distances over 300 feet or more. Such deployment allows for multiple wireless camera systems to utilize a single transmitter and fiber backhaul, maintaining high-quality transmission of audio and video signals even in complex event settings.

Remote monitoring and control (M&C)

RFOptic’s solutions come equipped with an independent graphical user interface (GUI) displaying both optical and RF levels in real-time. This monitoring capability aids broadcast teams in adjusting settings on the go, ensuring optimal performance during live events.

Deployment

Deploying the RFoF system involves the initial setup of the transmitter and receiver units, along with the installation of the single-mode fiber infrastructure. This streamlined deployment minimizes setup time, allowing broadcast teams to prepare quickly and efficiently for live events, while ensuring extensive coverage without the limitations of coaxial cables.

Conclusion

RFOptic’s optical RF broadcast solutions represent a significant advancement for broadcast companies seeking reliable, high-quality audio and video transmission during live events. With the ability to extend operational ranges, reduce maintenance costs, and simplify deployment, RFoF technology is the ideal solution for enhancing broadcast capabilities.
