Optus - The Network

Synopsis

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 to 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, non-business, customers. Digital switching facilities have been constructed in major cities, with fibre optic cable linking these exchanges. The company also has satellite facilities. The company launched its 3G services in Sydney, Canberra, Melbourne, Brisbane, Adelaide and Perth. By 2008 the network was being upgraded with HSPA technology to deliver broadband speeds of up to 7.2Mb/s.
