Fiber Optic Link GPS-over-Fiber

Description

Fiber Optic Link GPS-over-Fiber

The GPS-over-Fiber Link (GPSoF1 – 1.5GHz) offers a very high stability in addition to excellent performance in phase noise and frequency jitter in applications such as remote antenna connection in GPS receiving systems.

A separate Tx & Rx module is required for this solution.

Features:

  • For GPS L1 and Glonas L1 (L2 available on request)
  • No external control circuits required
  • Analog Signal to Optical convert and back

Applications:

  • Antenna remoting
  • Interfacility communication links
  • Reference Signal distribution

Potential Applications:

  • Single buildings requiring a point-to-point GPS solution. Point 1 being the GPS antenna on the roof of the building and point 2 being the GPS Receiver in the basement.
  • Multiple facilities (fixed and mobile) requiring a multiple-point GPS solution. (e.g. time synchronisation and antenna remoting)
  • Mines requiring a multiple-point GPS solution for signal distribution. (Daisy Chain Topology)
  • Subways requiring a multiple-point GPS solution for signal distribution. (Daisy Chain Topology)

Additional Information

  • 4 Port receiver available.
  • All modules are RoHS Compliant.
  • All modules are EMV protected.
  • DIN 35 brackets are delivered with each module.
  • Other brackets available upon request.
  • No MIL Standard with standard module.
    MIL and other certifications are possible upon request.
    (A qualification fee will apply to any certifications.)
  • Various racks and enclosures available.
  • All modules are single packaged.
