The OZ101 Series of Miniature, Broadband Optical Links are used for a variety of linear RF over Fiber (RFoF) Applications. The OZ101 Series are small, lightweight, cost-effective modular components. The Link delivers high Spurious Free Dynamic Range (SFDR) with operational frequencies from 30 MHz to 3.0 GHz. 

The OZ101 Series Link consists of individual Tx and Rx Modules, connected via optical fiber (usually Single Mode Fiber), which offers an excellent alternative to using coaxial cable systems. This solution provides significant improvement in the transport of high frequency RF signals in their native format, reliably, across a broad range of frequencies.

One of the key usages of these miniaturized RFoF Modules is in antenna radiation pattern measurements. Optical Zonu’s Fiber Optic Links enable the measurement of the radiation pattern of small antennas without any coaxial cable interference effects. The product family was designed to enable the testing of hand-held cellular telephones and emerging LTE (employing Antenna Diversity) devices, operating from the low voltage battery supply of the phone itself (down to +3.7 Volts). Experimental results have demonstrated that the use of legacy RF coaxial cable strongly disturbs the antenna gain and radiation patterns for both polarization components. With very simple integration, at a low cost, our OZ101 Series Links can characterize radiation patterns of both narrow and UWB compact antennas. Studies which compared both measured and simulated results, demonstrated excellent agreement (±1 dB) for co-polarization in the different cut-planes. With very low power level measurements, and at high frequencies, standard RFoF products, which are typically 3 inches by 5 inches, or larger, are considered too big to be used because they affect the antenna radiation pattern.

It is “best practice” to use miniaturized optoelectronic components, whose size does not materially impact the outline of the product under test powering the module is Via uUSB connector which also provides ROM readout capabilities for alars and operating conditions such as internal laser and photodiode among other parameters. The standard optical connectors are Angle-Polished (APC) for low back reflection operation. The Receiver features a high performance InGaAs photodiode and the Transmitter is based upon a linear Isolated DFB Laser operating at 1.3 or 1.5 μm (A) over 9/125 μm Single Mode Fiber. Average Automatic Power Control (AAPC) is incorporated for optimal optical power stability over the full temperature range. The RF interface is a 50 Ohm SMA connector. DC connector (incl. I2C link for internal control and Alarms) – Micro USB (B Type).
