Powering tomorrow´s data internetworking systems

The Telecoms evolution will require a number of new data internetworking equipment including high speed central processing units (CPU), digital signal processors (DSP) and high speed transmission routers and switches at 10 Gbit/s, or more, for LAN and WAN switching, Sonet and SDH systems. A mix of both fixed and mobile access network systems will be connected to this new common connectivity network´s access points. These new data internetworking equipment and access network systems will include cost sensitive on-board power solutions and distributed power architectures (DPA), using 48 V DC system voltage, will become the preferred power system solution. The power requirements for on-board DC/DC converters are ranging from 10 W per board, in telecom switching and cellular radio applications, up to more than 200 W per board, in high speed CPUs and high speed 10 Gbit/s routers. To manage and become a successful on-board power solution provider in this telecom evolution it will require close co-operation with the equipment manufacturers, to understand the different applications´ requirements, both technical skillness and resources as well as high manufacturing volumes and high automation levels to meet the technical requirements and the demand for improved cost/performance ratio
