System Types

Long Haul Systems (core networks, submarine systems)

Metro, Access Networks

Passive Optical Networks (PONs) (Fibre to the Premises (FTTP), Fibre to the Home (FTTH))

Radio on Fibre (RoF) Systems (Fibre wireless, RF photonic systems)

Those systems transmit radio frequency signals at microwave and millimetre-wave frequencies via optic fibre cable. Analogue and digital transmission is used.
