The OZ20x OEM fiber optic transmitter and receiver modules are broadband RF over Fiber standalone enclosed board level assemblies that are well-suited for low size/ weight/power (such as drone and UAV) applications. The OZ20x was specifically designed for very wide dynamic range (>60dB) and supports RF transport in situations where transport distance or flexibility of cabling may prohibit the use of coaxial cable.

Inline digital attenuators enable both transmitter and receiver RF gain control. Both Manual Gain adjust (MGC) and closed loop Automatic Gain Control (AGC) are supported in the fiber transmitters and receivers. MGC and AGC modes enable optimization of spurious free dynamic range (SFDR), noise figure, linearity (P1dB and IIP3), and RF gain over a wide variety of optical loss budgets and RF signal levels. Built-in RF shielding supports low EMI/RF interference.

Transmitters feature linear uncooled isolated DFB laser diodes. CWDM wavelengths are available. Average Automatic Power Control (AAPC) provides closed loop control of the transmitter optical output power over the full operating temperature range. Receivers feature high performance InGaAs photodiodes. The standard transport RF frequency band is 30 – 3,000 MHz. Options exist for extending the frequency range to 1 MHz on the lower end and 6 GHz on the higher end. The RF interface is 50Ω SMA. SC/APC optical fiber pigtails are standard to maintain low optical reflections throughout the fiber plant. Contact Optical Zonu for other options. Standard transport is over 9/125 μm single mode fiber, however Multimode fiber transport is also an option (contact Optical Zonu for details).

The OZ20x module power and digital interface is provided on an industry standard USB-C connector. Monitoring and control are via a USB, I2C, or UART physical interface. LEDs provide local status of fiber transmitter and receiver. OZ20x modules are powered from 6.5 VDC.

OZ20x transmitter and receiver modules may be integrated into 19” rack mounted architectures to provide very dense RF over fiber transport. Up to 64 transmitter and/or receiver modules can be fit into a 19” 3RU J3U Chassis by utilizing the J3U plug-in modules. (see the J3U Quad Transport Datasheet). RF links may also be optimized for transporting low phase noise reference clocks in the frequency range 10 – 200 MHz.
