OZ101 – Mini RFoF Link

The OZ101 is a miniature, light-weight pair that consists of individual Transmitter (Tx) and Receiver (Rx) modules, which when connected via optical fiber, creates a one-way fiberoptic, unidirectional link. It is an excellent alternative to using coaxial cable systems and offers affordable, versatile end user implementation along with significant improvements in transporting high frequency RF signals in their native format reliably across a broad range of frequencies. The link has High Spurious Free Dynamic Range (SFDR), with operational frequencies from 30 MHz to 6.0 GHz or more and offers Wi-Fi and broadband operations.

The OZ101 series of miniature broadband RF-over-Fiber laser links are used for variety of analog over fiber or linear RFoF applications. One of the key usages of these highly miniaturized RFoF modules is in antenna radiation pattern measurements. OZ101 helps in the accurate 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, while operating from the low voltage battery supply of the phone itself (down to +3.7 Volts DC).

The standard optical connector is SC/APC. FC/APC or LC/APC are available upon request. The Receiver of the OZ101 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 CWDM as well) over 9/125 µm single-mode fiber. The electrical connectivity is via mini-USB connector which enables monitoring via EEPROM emulation. Average Automatic Power Control (AAPC) is incorporated for optimal optical power stability over the full temperature range. The RF interface is via a 50 Ohm SSMB connector.
