Abstract
In this paper, high-density and large-capacity parallel data reliable transmission has been accomplished in high electro-magnetic interference environments via virtual- parallel optical transmission technique. Through time division multiplexing (TDM), all the parallel data signals and control signals are converted to high-speed serial data stream. Each bit is transmitted in a time slot during a frame period Thus, the parallel signals can be transmitted using only one opto-electronic device. Each optical transmission channel consists of two optical fibers, can achieve full-duplex transmission of 24 bits parallel signals. The maximum frame rate is 75 MHz. This data transmission card can be expanded to 6 channels, has a maximum data throughput of 15 Gbps. This optical data transmission link can work properly for a wide range of supply voltage. When the supply power voltage varied from 4.2 to 7.0 volts, the bit error rate (BER) is still below 10E-12.
