The optical fiber used to sharpen the CAN communications network antigambling ability as the transmission medium. Detailed subdivided Fiber-CAN correspondence connection design feasibility, and designed point-to-point network correspondence Fiber -CAN connection. It mainly has outside the monolithic integrated circuit control section, the monolithic integrated circuit supposes partially with the CAN correspondence connection partial compositions. The monolithic integrated circuit and besides supposed works together has had the CAN message center transmission information, another pitch point through demonstration partial demonstrations correspondence result. Fiber-CAN correspondence photoelectricity transformed partially uses SDH to receive and dispatch a body the photoelectricity transformation module, to have been partial compared with the easy realization optical fiber connection, reduced the design complex degree, and enhanced the system the performance. The optical fiber use not only enhances the correspondence greatly the antigambling ability, moreover has increased the pitch point transmitting range. This design proposal applies in the automobile bus line, can in the automobile the extremely bad scene stable transmission automobile each part parameters, complete each part of coordinated cooperation the duty.
