Abstract
An optical architecture for receiving and slowing down high-speed data for high-speed digital testing applications is provided in which an input generating means transmits high-speed input test vectors to an apparatus under testing. In response, the apparatus under testing generates output test vectors. These high speed output test vectors are converted to slow-speed data signals by optically demultiplexing the high-speed vectors into high-speed parallel data signals and then expanding the parallel data signals to for slow-speed data signals. The slow-speed data signals are then compared with slow-speed reference vectors on a personal computer to determine whether the apparatus under testing is in error for any of its output channels.
