An SDH-based optical transmission-system for applications in High-Energy Physics

We report on a concept of an optical transmission system with a baud rate of 2.488 Gbit/s that is based on the SDH-standard and complies with the severe requirements of High-Energy Physics-experiments. The smallest readout time per analog detector channel of 7.6 ns can be realized. A comparison with already realized concepts shows an improvement of the throughput capacity by a factor of at least 10. A novel parallel coding scheme and standardized interfaces guarantee a high flexibility and a simple development towards higher transmission capacities. The area and power requirements of the system are discussed for a suggested form of realization.
