Abstract

The design of an experimental single-channel 224-Mbit/s (megabits per second) optical pulse code modulation (PCM) terminal is described and data are presented which have been obtained with such a terminal using a helium-neon laser operating at 6328 Å. The basic elemets is an optical gate using lithium tantalate whose design and operating characteristics are described.
