Powering the Australian Optical Fibre Trunk Network

Over recent years, the rapid expansion and diversity of telecommunications services has created a rneed for a new approach to power system design. Telecom Australia has responded to this need by developing new power system concepts to meet these requirements more effectively. This paper describes the first of these new developments which are currently being introduced to power optical fibre trunk systems. A Rack Power System will be used at mains powered sites. This equipment is provided as a modular package which uses the space saving advantages of switch-mode rectifiers and recombination batteries. All equipment will be housed in a GRC clad integrated power shelter which is supplied complete with electrical services and wiring looms. The main characteristics of this new range of equipment are high flexibility, low provisioning lead times and minimal installation and maintenance requirements.
