Self Healing Fibre Network


Self Healing Fibre Network

Auto-Changeover Control Tower CNS

At London Heathrow, FTI's self healing Fibre Network
connects the Comms, Navigational Aids and Surveillance
systems to the Control Tower.

There are two Fibre Network Rings, one around the North
and the other for the South Runway. A break in a Fibre
Network Ring will self heal in <2 sec, to meet the ICAO
Standard for a CAT IIIb Instrumentation Landing System.

The self healing Fibre Network assists in maintaining the
high utilisation of both LHR Runways, where Aircraft
separation can be down to 2.5nm.

The 1240 CNS Multiplexer is a key component of the self
healing Fibre Network.
