Optus - The Network


Attention: There is an updated edition available for this report.

The Optus Customer Access Network comprises a fibre and HFC network.

The fibre network serves major business customers via Optus laid fibre in all capital cities, major suburban business districts and major regional centres, and also provides transmission capacity between the Optus network facilities (exchanges and fibre access nodes) and do many of Optus DSLAM sites.

The HFC network is a wholly Optus owned network used for telephony, high-speed data and pay television to residential and non-business customers. This network is to be progressively decommissioned from 2014-2018 as the HFC customers are moved across to the fibre-based NBN.

Digital switching facilities are in major cities, with fibre optic cable linking these exchanges. The company also has satellite facilities. The company operates mobile networks across Australia with 97% population coverage in 2012.

The company continues to move ahead with technology updates to its networks. LTE networks were launched in late 2012 following consumer trials in the 1800MHz spectrum. Further rollouts of LTE are planned further into 2013 and 2014.

Facilities to attract businesses to use cloud-based services over the IP network have been launched to make use of the new satellite Optus 10 to be built and launched in 2013.
