RFOptic’s GPSoF solution is a 5g module designed to distribute the GPS timing signals throughout various buildings with many locations to which the GPS signals must be brought in. The GPS signals are converted into optical signals that are distributed to various parts of the building, where they are converted back to GPS signals and connected to various timing devices. This allows one GPS antenna to provide timing signals to not only many parts of the building but also to far-flung corners of the building, which cannot be reached by coax cables.


Key Features

  • Programmable GPS Over Fiber modules
  • Broadband support from 0.5 MHz to 2.5 GHz including L1, L2, L5 frequencies
  • +5VDC Bias-T option with up to 250mA provides power to an active GPS antenna on the RF port.
