As is the case with all such projects, specialised cable laying ships aided in the deployment of the Prysmian-made optical fibre cable. (Image credit: TPG Telecom)

TPG told iTnews that :the project means an additional 1728 fibres are now serving the high-data demands of businesses and consumers in North Sydney and the CBD." (Image credit: TPG Telecom)

The harbour-based route is said to be six times shorter than conventional land-based routes carrying traffic between the two sides of the city. (Image credit: TPG Telecom)

TPG Telecom said the new route "also increases redundancy and diversity across the harbour, with TPG Telecom owning and operating two separate links over Sydney Harbour Bridge and Sydney Harbour Tunnel." (Image credit: TPG Telecom)
