RFOptic has launched its innovative controllable phased-matched 6GHz RFoF modules

At RFOptic, we listen to our customers to provide solutions that they want and need. So when we got requests for programmable phased-matched 6GHz solutions, it was a no-brainer for us to have our R&D department working on it. (To download the brochure, click here)

The palm-size analog RFoF modules are used to convert RF signals to optical signals to carry over long distances. The Tx unit using an optical transmitter, converts RF to Optical signal and the Rx unit converts back to the RF signal. The two units are connected through customer’s single-mode fiber.

RFOptic’s RF over Fiber modules (RFoF) are suitable for Phased Array Radar, Electronic Warfare, and interferometry applications. RFOptic CWDM 6.0GHz RFoF 4 link system is phase-matched up to ±6˚ up to 5.7GHz. Each of the four links is comprised of a Tx unit with LNA and an Rx unit, both with variable attenuators that enable adjustment of the Noise Figure, Input P1dB, and IP3 over a wide range of values. The LNA can be activated through an RFoF software tool allowing RF input power in the range of -100 dBm/1MHz for wideband applications, with low Noise Figure of 6 dB. The RFoF link has excellent gain flatness with 0.5dB gain tracking between different links.

A user-friendly RFoF software enables adjustment of the RF and Optical parameters, such as link gain, Noise Figure, P1dB, Optical power, LED indication, and module information, either locally or remotely. In addition, the phased-matched 4 links DDM has HTML/SNMP interface so management and monitoring can be done remotely

Furthermore, the RFoF link has full diagnostic capability, including Tx, Rx and complete link test (Optical and RF). These features save cost of test equipment and provide real-time diagnostic of any deployed link. The link gain calculator helps to calculate the link gain and the optical predicted parameters for RFOptic’s programmable RFoF family.
