Fibre to the premises – FTTP

Diagram representing the connection path of Fibre to the Premises (FTTP) between the Customer Premises and the Point of Interconnect (POI)
FTTP: Fibre to the Premises

Original technology preferences were FTTP, Fixed Wireless and Satellite.  Other options now include :-

  • FTTN – Fibre to the Node – utilises last km of existing copper cable to customer
  • FTTC – Fibre to the Curb
  • HFC – Hybrid Fibre Coax – utilising existing Foxtel PayTV Coax infrastructure.

Advantages of optical fibre transmission

  • Electrically intrinsically safe – can occupy same ducts/conduits as LV & HV power
  • Carries highest data rates ; higher than twisted pair and over longer distances
  • Very low transmission loss means long distances without boosters/repeaters (eg;150 km using single mode fibre)
  • Light weight cable
  • Immune to electrical interference from motors, transformers
  • Does not attract lightning
  • Does not cause ground loops when inter-connecting equipment in different buildings
  • Higher security against “taps” than twisted pair.
Visible light: 400 nm (violet) to 750 nm (red)

  • Fibre optic transmission:
  • non-visible infra-red 850nm (MM), 1300nm (MM), 1310nm (SM), 1490nm(FTTP), 1550nm (SM) & 1625nm (SM Testing)

Multi Mode is used for less than 2kms in customer premises, Single Mode is used in the Telco environment.
