GPS Fiber Optic Link

Optical fiber provides a cost-effective solution for long cable runs in GPS systems. The Optical Zonu GPS over Fiber Optics System allows signals to be carried from an antenna to a GPS receiver with minimal signal degradation over a non-conducting dielectric glass media. This system provides a completely transparent cross-site connection between an antenna and receiver. As is the case in many types of in-building environments, networks require accurate clock synchronization. By utilizing broadband RF-over-Fiber Optics (RFoF) Technology, Optical Zonu GPS over Fiber Optics Links provide easy to operate, low cost and reliable solutions that enable GPS signal distribution using fiber optic cable.

The broad bandwidth (47 MHz – 2.7 GHz) of the OZ800/600 series modules used in our GPS over Fiber Optic Link allows transmission of the two main signals in the GPS band, L1 and L2, at 1575.42 MHz and 1227.6 MHz respectively. These RF-over-Fiber links are designed to offer low noise figure by integrating a built-in LNA with Lasers featuring low Relative intensity Noise (RIN) and low loss broadband matching, in order to optimize the Link performance. Optical Zonu’s GPS over Fiber Link consists of stand-alone transmitter and receiver units. Each module is housed in compact (3 X 5 X 1.5 inches) metal ruggedized boxes which allow convenient installation in small spaces. Both units are powered via a DB-9 plug using +12 Volts DC (optional power supplies are available upon request).

Optical Zonu’s GPS over Fiber Link is an ideal solution for providing GPS timing and reference signals over fiber optic cable. It acts as a low loss extender between the GPS antenna and GPS receiver in places where GPS signals are otherwise unavailable, or where running long coaxial lines is impractical.
