【Abstract】 A multi channel data transmission card has been designed and implemented using synchronous optical transmission technique. This card uses VME bus interface, supports simplex and full duplex operation modes. The throughput of each channel is 2.5 Gbps. A pair of optical fiber is used as transmission media for each full duplex channel, it is functionally equal to a 96 core wire cable. Using this card, virtual ribbon function can be achieved and reliable data transmission can be assured in high electro magnetic interference environments.更多还原
