RF Over Fibre Systems
2.5GHz RF Over Fibre For GPS
RFOptic presents its new innovative controllable RFoF product line. RFOptic's 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 RF signal. The two units are connected through customer’s single mode fibre. RFOptic's RF over Fibre modules (RFoF) are suitable for telecommunications, satellite, radio telescopes, distribution antennas, broadcasting audio and video, timing synchronisation and GPS applications. For example, point-topoint antennas can be connected from several meters to many kilometers away from the control room by fibre cables; Base stations can be connected through fibre to remote sector antennas; Satellite antennas can be connected through fibre cable to remote sites by RF over Fibre solutions.BBN International supplies RFOptic 2.5GHz RF Over Fibre For GPS Module
Altimeter RF Over Fibre Optical Delay Line System
RFOptic's high frequency Altimeter Optical Delay Line (ALT ODL) provides a high-performance solution for testing and calibration of radar altimeter systems. The RF input signal is converted into a modulated optical
signal, which is then transmitted into a single mode fibre, creating a fixed time delay defined by the fibre length corresponding to a desired altitude. After passing through the fibre, the optical signal is converted back into an electrical RF signal, identical to the input RF signal.
The ALT ODL can be configured to emulate a single altitude or
up to 4,096 altitude steps. RFOptic's ODL unit is a compact solution, which provides superb signal performance and altitude simulation accuracy with an ultra-silent operation.
The control and monitoring is done using a front panel, a navigation switch, and a LCD display, or via a USB connection using RFOptic’s configuration tool software. USB API is available for automated testing applications as well as Ethernet remote management with RFOptic’s HTML/SNMP/REST remote management solution.
The Altimeter ODL offers very high accuracy up to 0.3ns for altitude steps under 2mand > 0.1% above. The maximum altitude can reach 30km in one enclosure.

High SFDR RF Over Fibre Systems
The MiniQ series addresses the need when a wide range of spurious-free dynamic range (SFDR) is desirable when multiple signals of very different power levels are expected. RFOptic’s MiniQ 18GHz, 20GHz, 30GHz, and 40 GHz RFoF solutions provide high SFDR of minimum 112 dB/Hz. Applications include distributed antenna, satcom, radio telescopes, EW, and communications.BBN International supplies RFOptic High Spurious-Free Dynamic Range (SFDR) RF Over Fibre Systems
RF Over Fibre Converters
Analog RF over Fibre modules convert RF signals to optical signals and back. One unit has an optical transmitter which converts the signal from RF to Optical, and a second receiver unit converts the signal from Optical to RF. Both units are connected by the optical fibre of the customer.RFOptic offers two groups of RFoF modules: low frequency (0.5MHz – 6GHz) and high frequency 8GHz and up to and including 40 GHz) programmable RFoF solutions.
The low frequency programmable RFoF modules (also with SNMP) are based on direct modulation and include 2.5GHz (with optional GPS), 3GHz, 4GHz, 6GHz.
Other options include: Bidirectional (2-way) over Fibre 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.
Frequency range of 0.5MHz to 6GHz with excellent flatness, >40dB gain links, and NF around 5db with LNA On.
Applications include remote antenna, GSM and cellular communications, broadcast, and satellite.
The high frequency RFoF modules are based on indirect modulation and include 8 GHz, 15 GHz, 18 GHz, 20 GHz and 40 GHz.
Frequency range of 10MHz up to and including 40GHz with good flatness and good phase noise. The NF gain can be improved by adding an amplifier. Parameters such as Gain, P1dB and Noise Figure can be modified upon request.
Applications include remote antenna, EW, radar, and military communications.BBN International supplies RFOptic 2.5 To 40GHz RF Over Fibre Converters

Switchable RF Optical Time Delays
RFOptic provides any fixed time delay between 0.1 and 300 μsec (fixed). At special request, >300 μsec can be provided. The ODL is operated as a standalone unit with no need for any intervention by the operator. It can also be controlled externally from a PC through various communication interfaces.In general, we offer two groups of ODLs:
1) Any type of fixed, variable, or mini ODL up to 6GHz with direct modulation (L, S, & C bands)
2) Any type of fixed, variable, or mini up to 40 GHz with indirect modulation (X, Ku, & Ka bands).
Options include: 6GHz, 8GHz, 15GHz, 18GHz, 20GHz, and 40GHz. 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), Mini Optical Delay Line (a compact desktop module that supports a single delay line of up to 15us), and RFOptic’s ODL 2U Box series for testing and calibrating radar systems or for RF communication.
