A computer system for analysis of high capacity components in optical-fiber links

The system includes an HP 21MX minicomputer with a 32K main memory and a disk, making it possible to handle easily 4096 data points in both the time and the frequency domains. The modular organization of the software and the command file control of the processing have created a flexible system that has proved to be useful in evaluating models of semiconductor lasers and avalanche photodiodes. Furthermore, the system has been used to develop modulation methods for semiconductor lasers in the gigabit per second range.
