Abstract:IEEE1394b is a highspeed serial bus, with strong realtime, high reliability and wide application. Optical transmission technology has characteristics of strong anti interference ability and long distance transmission. This paper designs and implements a data optical transceiver module based on the combination of both advantages. Applying FPGA as the core controller, this module builds PCI bus controller with the technology of system on chip to achieve the control of IEEE 1394b link layer interface, realizes the DMA driver development of embedded system based on IEEE1394b’s isochronous transmission mode and achieves the conversion circuit from electricity to light of IEEE1394b physical layer utilizing circuit simulation based on PSpice. Meanwhile the implementation of the protocol mapping from IEEE1394b to fiber channel realizes the interconnection between IEEE1394b and fiber channel and also works out the limitation of IEEE1394b bus network topology. The module is able to adapt the embedded, highspeed, longdistance and realtime demands of data acquisition systems.
