F-GPSF GPS Over Fiber Optical RF Transport System

F-GPSF   GPS Over Fiber Optical RF Transport System

The F-GPSF GPS over fiber system is a transmitter and receiver pair used to transmit the RF Carrier signal from a GPS antenna to a remote location up to 10 Km. There are many advantages to converting the GPS Carrier to an optical signal for GPS over fiber. Fiber Optic cable is much less expensive than low loss coaxial cable used for RF signals.  It is also much smaller and easier to work with. Optical signals are not affected by RF interference, therefore this system can be used to transport a GPS signal over fiber through a noisy RF environment. The F-GPSF can also be used to transport the GPS signal over fiber from a single GPS antenna to a multitude of locations throughout a building, aircraft, or ship.  

Product features

 • Minimal signal loss and degradation over very long cable runs upto 10km.
 • Provides a highly secure tamper-proof GPS over fiberconnection between antenna and receiver.
 • Interference free link through noisy environments, the optical signal is unaffected by electical noise.
 • Flexible, small-diameter, lightweight optical fiber cable for GPS over fiber.
 • Lower cost of optical fibre cable compared with long cable runs of high quality low-loss coax.
 • Electrical isolation between antenna and recever protects against lightning strikes and electrical surge
