RFoF – RF over Fibre Optic

RF over Fibre (RFoF), sometimes called RF over Glass (RFoG), is a mature technology becoming increasingly popular across many industry sectors such as Defence, Satcom, Broadcast, Infrastructure, Telecommunication and Mining.

RFoF is well suited for applications where distance or other factors become problematic with traditional coaxial cable installs. RFoF is used to connect antennas to transmission and receiving equipment. Rojone and our US partner Optical Zonu can provide a wide range of solutions from day to day in building conversion to more complex demanding solutions challenges. With a frequency range suitable for transporting across all HF, VHF, UHF, L, S, C, X, Ku, K and Ka bands (10 MHz to 40 GHz).

Advantages

The transmission of RF and Microwave Signals via waveguides or coaxial cable suffers high insertion
loss and susceptibility to interference (EMI). Single Mode RFoF transceivers provide an excellent alternative for this type of application. Fibre Optic transmission offers significant advantages for the reliable transport of RF signals in their native format over many optical networks and across a broad range of frequencies. For analogue type signals, especially at high frequencies, premium performance at high Spurious Free Dynamic Range (SFDR) is desirable.

  • Less signal degradation per meter
  • Higher signal carrying capacity/bandwidth
  • Less costly per metre
  • Lighter and thinner than traditional coaxial cable
  • Free from electromagnetic interference (Poor weather does not affect signal)
  • Lower transmitter launching power

Applications

  • Cellular wireless
  • Public safety
  • Network sync
  • Satellite earth stations
  • Defence applications
