Signal Quality with RF Over Fiber

Long-Distance RF Transmission

You need reliable rf performance over long distances. rf-over-fiber gives you a clear advantage. You can send rf signals across vast distances without worrying about signal loss or degradation. SM28 fiber, used in leading rf-over-fiber systems, delivers extremely low loss—just 0.25 dB per kilometer at 1550 nm. This means you maintain signal integrity even when your network stretches for miles.

• You can trust rf-over-fiber for secure long-distance signal transmission.

• SM28 fiber ensures your rf signals stay strong and clear.

• You avoid the heavy losses that come with traditional coaxial cables.

You get support for a wide range of frequencies. Modern rf-over-fiber solutions handle everything from 5 MHz up to 6 GHz, covering both analog and digital signals. This flexibility lets you use one system for many different rf applications, from broadcasting to wireless communications.

Minimizing Loss and Interference

You face many challenges with traditional rf transmission. Coaxial cables introduce noise and attenuation, especially as distances increase. This can lead to poor signal-to-noise ratios and unreliable connections.

Traditional rf transmission faces significant signal degradation primarily due to the limitations of coaxial cables, which introduce noise and attenuation. For instance, coaxial cables can have losses ranging from 3 dB to 5 dB per 100 m in the 10 MHz to 100 MHz range, and up to 25 dB per 100 m from 100 MHz to 1 GHz. This degradation is exacerbated by the low received signal power and the presence of noise, leading to poor signal-to-noise ratios. In contrast, rf-over-fiber technology utilizes low-loss optical fibers to mitigate these issues, effectively replacing coaxial cables and improving overall signal integrity.

With rf-over-fiber, you eliminate these problems. Fiber is immune to electromagnetic interference, so your rf signals remain stable even in environments with high electrical noise. You also benefit from high linearity and a wide dynamic range. This means your system can handle both weak and strong signals without distortion, which is essential for demanding rf applications.

You can count on rf-over-fiber for long-distance links that deliver consistent, high-quality performance. You get the best of both worlds: the high-frequency capabilities of rf and the reliability of fiber. This combination makes rf-over-fiber the smart choice for anyone who values signal quality and secure long-distance signal transmission.

RFoF Reliability and Performance

You see these benefits in action during field testing in environments such as aircraft, industrial sites, and military bases. RFoF systems provide the flexibility and scalability you need to expand your network without sacrificing optimized performance.

Immunity to Electromagnetic Interference

You face many challenges when deploying RF systems in areas with high electromagnetic activity. Traditional copper-based cables, like coaxial, are vulnerable to electromagnetic interference and radio frequency interference. This vulnerability can lead to signal distortion, data loss, and security risks.

Fiber solves these problems by providing complete immunity to electromagnetic interference. You get reliable data transmission, even in environments filled with electrical noise. Fiber does not emit electromagnetic signals, making your communication links undetectable and resistant to jamming. This feature is especially valuable in military and industrial applications, where secure and interference-free signals are critical.

You also benefit from enhanced security. Fiber is naturally resistant to eavesdropping, which protects your sensitive information. The U.S. military relies heavily on fiber technology for these reasons, accounting for a significant portion of global demand.

With RF-over-fiber, you achieve consistent, high-quality RF transmission in any environment. You can count on stable operation, robust security, and immunity to interference, ensuring your system delivers the performance you require.
