Paper Abstract

Photonic systems are already commonly deployed for the efficient transmission of huge amounts of data in both long haul and access networks. It is generally assumed that optical technologies will also enable the construction of ATM switches of very high capacity. While research continues into devices and techniques aimed specifically at switching applications, this paper presents an approach which is based on direct re-use and adaptation of technology elements from transport, in the construction of a very high capacity ATM switch. The architectural principles are, broadcast and select, and the grouping of ATM cells into larger bursts, transmitted at very high speed. Passive optical techniques are very effectively employed to replicate, and distribute the signals, while a selection of active photonics, in combination with electronics provide the switching, buffering, and control functions. The switch architecture provides a rich field for the application of various optical devices to increase throughput, and reduce cost. At the same time, advances in electronic technology evolution, such as faster logic and memory circuits, can go hand in hand with new photonic developments to reduce the size and power requirements of very high capacity switching systems.
