This single-output optical receiver provides a dedicated connection between a remote GNSS antenna location and GPS or GNSS equipment through a fiber-based link. It receives the optical signal from the connected transmitter, converts it back into RF, and delivers the recovered GNSS signal directly to the receiver antenna port. This architecture supports installations where antenna placement needs to be separated from navigation, timing, synchronization, or reference equipment.

Designed for direct GNSS connection applications, the receiver supports GPS L1/L2/L5, Galileo, GLONASS, and BeiDou services across a 1100–1600MHz RF range. Variable RF gain enables signal-level adjustment during system commissioning based on optical link loss, RF cable characteristics, and the input requirements of the connected receiver. Compatible antenna options can be selected from the GNSS Antennas category for different installation requirements.

How does the Single RF Output receiver connect a remote GNSS antenna source to receiver equipment?

The receiver converts the fiber-delivered GNSS signal back into RF and provides one SMA RF output for direct connection to a compatible GPS or GNSS receiver antenna port. This maintains a dedicated signal path between the remote antenna location and connected equipment.

What equipment can use the recovered GNSS signal?

The RF output is designed for compatible GPS and GNSS equipment that accepts antenna input signals. Applications may include navigation, timing, synchronization, and reference systems.

How does variable RF gain support receiver integration?

Variable RF gain up to 44db enables adjustment of the recovered RF output level during commissioning. The configured level should consider optical loss, RF cable characteristics, and the input requirements of the connected receiver.

Does this receiver provide a GNSS re-radiation output?

No. The RF output connects directly to a compatible GPS or GNSS receiver antenna port. It is designed for direct GNSS connection applications rather than feeding indoor transmit antennas for signal re-radiation.

What factors affect the achievable fiber distance?

The supported fiber distance depends on the total optical link loss, including fiber attenuation, connectors, and other passive optical components. The complete link should remain within the specified 3db optical budget
