The RFoF-4.0GHz from RF Optic are Programmable RF Over Fiber Modules that operate from 0.5 to 4000 MHz. They are used to convert RF signals to optical signals to carry over long distances. The Tx unit using an optical transmitter converts RF to an Optical signal and the Rx unit converts it back to an RF signal. The two units are connected through customer’s single mode fiber. All units can be monitored and managed remotely with RFOptic’s unique SNMP/HTML capability.
Both the Tx and Rx units have integrated LNAs and variable attenuators that allow users to adjust noise figure, input P1dB and IP3 with wide dynamic range values. When the is LNA enabled, it provides an adjustable link gain of up to 42 dB with a noise figure of 6.5 dB and has an SFDR of 100 dB/Hz. This 50/75-ohm module supports laser diode wavelength of 1.31/1.55 μm and 2.3 (± 0.5) mW of optical power in the fiber. It requires a DC supply from 5 to 12 V, consumes 260 mA of current in Tx unit and 225 mA of current in Rx unit.
The RFoF-4.0GHz has a user-friendly software that 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. It also has full diagnostic capability including Tx, Rx and complete link test (Optical and RF) that save cost of test equipment and provide real time diagnostic of any deployed link. For special applications requiring temperature stability operation, a unique algorithm has been developed.
The module is available multiple configurations and is suitable for use in telecommunications, satellite, radio telescopes, distribution antennas, broadcasting audio and video, timing synchronization and GPS applications.
