| Abstract: | With the development of space remote sensing payloads,a high-speed data bus is strongly required for the huge amount data.For high reliability requirement of space environment,a novel fiber-optic bus architecture based on the command/response protocol,which combines FC-AE-1553 and passive optical network technologies is put forward.A ground verification system has been set up by using a redundant topology with double rings in inverse directions.The experiments show that the new bus system can reach a data r... |
