These RF over Fiber transmitters and receivers are relatively compact modules with various frequency ranges between 8GHz and up to and including 40 GHz. The electrical interface and dimensions can be tailored per customer request. Features include various RF gains, P1dB, noise figure by adding amplifiers, high P1dB`13 dBm and RS-232 communications. Enclosures can be unidirectional or bidirectional.
These broad spectrum solutions are RFoF links with Low Noise Amplifier (LNA) and attenuators which can be adjustable, or “programmable”, through the GUI. This enables the user to modify the System Gain, S21, P1dB compression point, and Noise Figure (NF) levels. The Noise Figure of these links can be as low as 5 dBm. Tx and Rx modules are quite small fitting into the palm of a hand. The units can be monitored and managed remotely with RFOptic’s unique SNMP/HTML capability.
Options include: 2.5GHz RFoF with optional GPS (0.5MHz – 2.5GHz), 3.0GHz RFoF (0.5MHz – 3.0GHz), 4.0GHz RFoF (0.5MHz – 4.0GHz), 6.0GHz RFoF (0.5MHz – 6.0 GHz). Other options include: Bidirectional (2-way) over Fiber receiver (2.5GHz – 6.0GHz), RFoF multi-link series (0.5 MHz – 6.0 GHz), CWDM 8 channel multiplexer (mux) / demultiplexer (demux) devices, and Bidirectional RFoF Picosecond.
In general, we offer four groups of ODLs:
- Any type of fixed or progressive ODL up to 6.0GHz with direct modulation (L, S, & C bands)
- Any type of fixed or progressive ODL up to 12.0GHz – 18GHz with indirect modulation (L, S, C, X, & Ku bands).
- Any type of fixed or progressive ODL of up to 20GHz, up to 27GHz and up to 40GHz upon request.
- Altimeter Optical Delay Line (ALT ODL), providing a high-performance solution for testing and calibration of radar altimeter systems
Other options include: variable ODL, also known as “switched ODL” or “progressive ODL” which supports up to 12 distinct delay lines (when hundreds of delay combinations are needed).
Our small size analog RFoF cards are available for companies who need RF over Fiber technology in their products (high volumes of at least a few hundred units).
This card, either Tx or Rx, comes as a board with optical, RF connector and DC interface. A control/diagnostic port is available in a small size micro USB interface on board.
Options include: 0.05 MHz – 2.5GHz, 0.05 MHz – 3GHz, 0.05 MHz – 6GHz.
Our user-friendly RFoF software enables monitoring and adjustment of the RF and Optical parameters, such as link gain, Noise Figure, P1dB, Optical power, status LED indication and module information, either locally or remotely.
