A leading vendor of digital and analog signal transmission system for optical fiber links, Optical Zonu Corporation, has recently introduced OZ1600, a high broadband optical transceiver that can be used for ‘RF over Fiber Optics Links.’ This transceiver can operate up to 7 GHz and has excellent flat frequency response. It is housed in a tight cast metal housing that is dust proof. It also has an integral WDM option for duplex transmission using SMF-28 single mode fiber.
Major characteristics of the product include rugged simple modular package, 20MHz to 7GHz operational range, high linearity, and excellent noise performance, increased temperature range of operation, stable gain, and flat frequency response.

As the laser transmissions’ analog RF parameter is dependent on the laser diode’s
operating temperature, transceivers like the OZ1600 can use a TEC, which is able to lock the laser temperature at a constant level, resulting in the stabilization of the relative intensity noise (RIN), laser wavelength, and optical power. This new generation transceiver is able to function over a wide range of temperatures (+65°C to -20°C) and less than 2 dB of gain variation.
The SC/APC (APC/FC is now available) is the standard optical connector for applications relating to low back reflection, such as analog video, and long haul digital transmission of data. The multimode fiber compatible version is optional and available on request.
OZC’s Director of Sales, Soyola Baasan, informed that using such linear type of transceivers enable RF systems components to be separated physically, which transmission lines or coaxial cable are not able to provide. He added that many applications that benefit from this technology are antenna remoting, distributed emitter systems, Satcom, GPS distribution, DAS, and frequency signal transmission on optical fiber system that demands low phase noise, 4G LTE, Wi-Max, or other applications requiring transmission of RF signals on optical fiber stably and dependably, in spite of ambient temperature variation.
