| Abstract: | An optical 155Mb/s pulse pattern generator with USB interface was introduced. Pseudorandom and other pattern pulses were generated by the computer then assessed the dual-port ram though USB. The pulses would be transmitted by an optical transceiver after parallel to serial converted. With the system, the pattern of the pulses can be chosen freely. The device has both optical and electrical interfaces, and can be used in all kinds of optical experiment. It is really a cost and feature optimized device. |
