Optus upgrades cross-continent fibre network to 100Gbps

15 Sep 2015

Australia’s Optus has announced that its inter-capital fibre network, which stretches from Cairns to Perth via Brisbane, Sydney, Canberra, Melbourne and Adelaide, has been upgraded to 100Gbps. The infrastructure now delivers wavelength capacity ten times larger than previously available, utilising French-US vendor Alcatel-Lucent’s 1830 Photonic Service Switch and Photonic Service Engine (PSE)-based coherent technology with soft-decision forward error correction (SD-FEC), which is able to extend the reach of 100G signals to 3,000km (1,800 miles) or more without need for costly re-generation. Work on the upgrade began in late 2014, linking Perth to Sydney, with Optus said to have made the strategic decision to move from 10Gbps straight to 100Gbps per wavelength ‘as a key technology step to even higher speed services’.

Rob Parcell, managing director at Optus Wholesale, Satellite and SMB, confirmed that the capability has already commenced rollout into Optus’ extensive metropolitan networks.
