What is RF over fiber technology and what are its advantages?

Radio frequency over fiber (RFoF) is a method of converting radio waves (RF) into light by modulating the intensity of a light source (usually a laser) with a radio frequency signal. This is an analog process, no digitization was used.

The optical signal is then transmitted through fiber optic cables, replacing and surpassing the capabilities of traditional copper coaxial cables.



Unlike coax, which is limited to 300 feet (approx.), you can extend the link up to 600 kilometers (373 miles) without affecting signal performance.



The advantages of RFoF are:


Very low signal loss (less than 0.5 dB/km)


Allows connections for kilometers without zooming in


Flat frequency response across frequency band


means no slope compensation is required


Immunity to EMI and RFI


Since fiber is a non-conductive medium


Security against signal interception


Flexible and lightweight


For ease of deployment


low maintenance


install and forget technology


easy installation




Compared to high end, low loss coax and slope compensated amplifiers.
