Optus Boosts Bandwidth on Key Fiber Links; Fujitsu Equipment Gives Carrier More Than Twice the Capacity.RICHARDSON, Texas--(BUSINESS WIRE)--Aug. 20, 1997--Optus Communications of Australia has more than doubled its capacity on key telecommunications links Uplink For other uses, see Uplink (computer game) and . An uplink (UL or U/L) is the portion of a communications link used for the transmission of signals from an Earth terminal to a satellite or to an airborne platform. An uplink is the inverse of a downlink. between Sydney and Melbourne by installing advanced fiber-optic networking equipment from Fujitsu. Optus, a five-year-old competitive carrier, recently put the 2,300-kilometer (1,429-mile) fiber ring into service, after Fujitsu put the equipment in place to make it possible. The ring now has the capacity to transmit voice, data and video traffic at a rate of 10 billion bits of data per second, or enough to handle 129,000 simultaneous telephone calls. The additional capacity will be used to support the growing Optus business, the rising demand for wholesale services, as well as the growth of Optus' advanced ATM network and MultiNet services. "The increased capacity on our busiest network route will cater for the anticipated increase in demand in the newly deregulated market," Cliff McElveen, Optus Group Technical Director said. "The advancement in network technology has been phenomenal. The Optus Sydney to Melbourne route now has 64 times the capacity per fiber that optical fiber networks were able to support just 10 years ago. "Optus has worked closely with our strategic supplier Fujitsu to achieve this great result" McElveen said. "The completion of this network expansion shows Australia is capable of leading the world in the deployment of technology to support growing market needs. A strategic relationship between carrier and supplier is critical to meeting such challenging tasks." The system is based on the FLASH(tm)-192 multiplexer See multiplexor and multiplexing. multiplexer - multiplexor from Fujitsu Network Communications. The product, Fujitsu's most powerful, is able to move data at 10 gigabits, or billion bits, per second. Also in use in Optus' ring is optical amplifier A device that boosts light signals in an optical fiber network. Unlike regenerators, which have to convert light to electricity in order to amplify it and then convert it back again to light, the optical amplifier amplifies the light signal itself. technology that enables distances between repeater (1) A communications device that amplifies (analog) or regenerates (digital) the data signal in order to extend the transmission distance. Available for both electronic and optical signals, repeaters are used extensively in long distance transmission. stations of greater than 150 kilometers (93 miles). That reduces the number of elements needed to build the network. The network is set up in a "diverse path," with sets of fibers running along different routes between the two cities. This arrangement provides automatic protection for the traffic on the ring and assures service even in the event of an accidental fiber cable cut or an equipment failures. One path runs along the Pacific coast, while the other is located inland. Different Fujitsu teams were responsible for each of the two paths. John Kranenburg, executive director of telecommunications Communicating information, including data, text, pictures, voice and video over long distance. See communications. and technology at Fujitsu Australia Ltd., observed that "Optus has again shown it is capable of deploying the latest equipment across the vast geographical distances of Australia. Fujitsu has been involved with all major transmission deployments by Optus since 1992 and is proud to support their continued success in this marketplace." The Optus fiber-optic network includes routes from Brisbane to Perth, passing through Sydney, Canberra, Melbourne and Adelaide. There is also a digital radio link between the major cities in Tasmania. In each major capital city, Optus has switching centers A switching center is a node in a telecommunications Circuit switching network which is connected to either another switching center and/or to end user devices. Switching centers are aware of other centers and possible routes between them such that on demand a center can establish and central business district fiber-optic rings. These rings provide direct access to Optus' corporate and government customers. The Optus Vision broadband local access network also connects into these rings. Optus Communications was selected as Australia's first private telecommunications carrier in 1991.
