Optical Zonu takes a modular approach to product design and development. The most basic building blocks are pigtailed OEM boards. Optical Zonu integrates these boards into higher level COTS and/or custom assemblies. Optical Zonu also makes these OEM boards available as building blocks for our customers’ designs.

The smallest pigtailed board is the OZ10x fiber transmitter and receiver. These modules weigh just 19 grams, occupy an envelope of 0.7” x 1.6” x 0.3”, and are powered from 5V – ideal for low size/weight/power applications. The OZ10x was initially developed to transport cell phone antenna pattern measurements from within anechoic chambers. Indeed, they may be powered from a mobile phone. Fiber is preferred within anechoic chambers due to the absence of radiated EM energy from the fiber. These small OEM boards may transport 1 – 6000 MHz and they have an I2C serial interface to accommodate integration into larger systems. As an example, the OZ10x may be packaged into J1 sleeves, providing optical and RF bulkhead connectors on the front. A blind mate connector on the back of the J1 accommodates plugging into a 19” 1RU J-Chassis. Such a high density implementation accommodates up to 45 fiber transmitters and/or fiber receivers per 1RU.

All Optical Zonu board level assemblies have an I2C or other serial communication interface (except for the basic OZ51x boards). When integrated into higher level Optical Zonu assembles (e.g., 19” chassis, outdoor enclosures, etc.), the user interface presented is SNMP v2/v3. SNMP supports a simple HTTP Web UI, Optical Zonu’s Managed RFoF graphical user interface (GUI), an SSH command line interface, and support for a RESTful API.

The KU18 and OZR18 are Optical Zonu’s higher frequency (X- and Ku-Band) board level building blocks. Cooled laser diodes support 100/50 GHz spaced DWDM channels to facilitate optical amplification for high insertion loss applications such as high split counts and rotary joint transport. Small SWaP accommodates dense packaging requirements. Variations of these (up to 18 GHz) parts are found within Optical Zonu flange mount, 19” 1RU pluggable, and IP67 outdoor enclosures.

The OZ51x is Optical Zonu’s most basic pigtailed board. This board is fixed gain (with or without transmitter LNA), is powered from 12V, has no I2C serial interface. The board does have open collector alarm and analog monitor pins for basic status. The OZ51x is capable of transporting 10 kHz – 6 GHz, and may be integrated into the 19” 1RU pluggable J400, the OZC9500 1RU chassis, and the eFiberSAT antenna remoting kit.

The enhanced OZ52x adds 30 dB tuning range inline digital attenuators and an I2C control interface. RF power monitors and AGC options may be added as well. The OZ52x is capable of transporting 10 kHz – 6 GHz. The OZ52x pigtailed boards are integrated into the 19” 1RU pluggable J500, the OZC9500 1RU chassis, the eFiberSAT antenna remoting kit, and the eT enhanced outdoor enclosure.

The OZ20x pigtailed OEM board is is similar to the OZ10x in size. The OZ20x adds various serial communication interfaces, inline digital attenuators with 30 dB tuning range, RF power monitors, and manual/AGC. The OZ20x adds the capability of being operated in FDD mode or TDD mode. Optical Zonu integrates up to 4 x OZ20x into a J3U chassis plug-in. The J3U provides and SNMP interface to the OZ20x building blocks. When integrated in this way, up to 64 modules may populate the front of a 3RU chassis.

These architectures can be custom tailored to specific applications. Depending on how much redundancy or capacity is required, the same commercial components can be added or removed to a system to meet specific needs.
