Optical fiber provides a cost-effective solution for long coaxial cable runs in GPS systems. The Optical Zonu GPS over Fiber for Network Sync 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 linear (analog) 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 (20 MHz to 3.0 GHz) of the RFoF transceivers used in our GPS over Fiber Optics Link allows transmission of the two main signals in the GPS band, L1 and L2, at 1575.42 MHz and 1227.6 MHz respectively. This GPS over Fiber Link is designed to offer a 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 RFoF Link consists of stand-alone analog (linear) transmitter and receiver units. Each module is housed in a compact (3 x 5 x 1.5 inches) metal ruggedized box 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 RFoF 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 cable lines is impractical.
