RF over Fiber for Satcom

RFOptic’s RF Over Fiber optical links are used for Satellite Communication Signals (Satcom) signals.

The links transport the IF signal down-converted from an original satellite signal feed for applications such as Intra-Facility Links, LNB, and fixed satellite.

Typically, the RFoF Satcom links receive the down-converted satellite signals from a remote antenna and carry them over to other locations, which can be several kilometers away. Transporting such signals over fiber optic cable has advantages over using coax cable particularly for longer distances.

RFOptic’s modules allow for the following frequencies: 0.5 MHz – 2.5GHz / 0.5 MHz – 3GHz / 0.5 MHz – 6GHz. In addition, we provide RFoF modules at 8,15,18 and 20 GHz using mach-zehnder modulators.

Optical fiber supports very long cable distances, up to a few kilometers, with minimal signal loss and degradation. Satcom applications use a Low Noise Figure RFoF link to transport such signals without  noise contamination. RFOptic provides built-in Low Noise Figure amplifiers in the RFoF transmitter to reduce the link NF up to 6 dB. This improves the signal quality substantially for these kinds of applications. In addition, gain attenuation in the Tx and Rx enables to tune the links to the desired parameters.

RFOptic offers a wide range of products in a variety of form factors for various Satcom applications. It can come as a compact stand alone module or up to 4 modules in 1 unit, or 8 modules in a 2 unit removable panel that houses a control card. Management can be done remotely.
