Demand for the transport of RF communications signals over Fiber Optic Links is rapidly increasing, driven by optoelectronic technology advances and the leverage of cost efficiencies of the optical telecommunications industry. Unlike coaxial cables, advances in fiber-optic technology now make it possible to transmit RF signals cleanly over extended distances without excessive insertion loss. Links with frequency coverage from 1 kHz to 50 GHz are supported, while maintaining extremely low noise figures, very high SFDR and extremely flat amplitude responses over frequency.
With this approach, it is possible to route Microwave/RF signals long distances, to remote locations, so that the receiver/processing hardware no longer has to be located within close proximity to the antenna. This also allows the receivers to be utilized in a pooled configuration serving multiple antennas, resulting in the potential for a smaller number of receivers for a multi-aperture system. By combining multiple antenna bands at light versus traditional RF combiners, a broadband feed can be formed that has no inter-modulation products at the band crossover points and only a slight (less than 1 db) degradation in noise figure. This provides the capability to tune a single receiver through a wideband optically mux’d signal derived from multiple narrower band antennas.
Finisar’s family of RF over Fiber products deliver the industries highest performance and can be optimized for very specific applications. Our complete product line includes compact modules, outdoor and wall mount units, as well as 1U and 3U modular, rack mount and custom systems. These products leverage Finisar’s world class laser and receiver product portfolios developed for ultra high-speed digital communications. Transmitters, Transceivers, and Transponders for Datacom and Telecom Applications are also available. These products are fully compliant with Ethernet, Fibre Channel, SONET/SDH/OTN and PON standards and operate at data rates up to 100 Gb/s. Finisar’s high-performance Analog, Datacom and Telecom products address the most challenging requirements of today’s modern networks.
