| Abstract: | This paper analyses the topologies,transfer protocols and message latencies for LTPB and FDDI fiber optic data buses.The LTPB is designed for avionics,which has features of low power consumption,high fault tolerance and real time capability.It will be main bus system used on flight vehicles in the future. The FDDI could support large scale network,has mature technique and low cost features.It can meet the needs of large commercial aircraft. |
