FirstPath will lay two lengths of submarine cable across Sydney Harbour containing 720 fibre cores, the densest underwater cable ever laid in Australia. This reflects growing demand for FirstPath's services. For manufacturer Prysmian, it is the second landmark high-density cable project in recent weeks. The project involves planning permits and crews to lay the cable after peak ferry hours to avoid interference. It demonstrates FirstPath's expansion from initial Sydney infrastructure to considering expansion along Australia's east coast.
