The small explorer (SMEX) project at Goddard Space Flight Center (GSFC) launched the first spaceflight implementation of the MIL-STD-1773 fiber optic data bus on the Solar Anomalous Magnetospheric Particle Explorer (SAMPEX) in July of 1992. The Small Explorer Data System (SEDS), of which the MIL-STD-1773 data bus is a part, has been successful. The MIL-STD-1773 bus is the implementation of the MIL-STD-1553 protocol using fiber optics. Advantages of the fiber optic bus over the electrical bus include lower power, lower weight, and immunity from EMI/RFI. It does not radiate electrical or magnetic fields. It is a nonconductor so it cannot conduct electrical noise into or from a subsystem. This is particularly advantageous on a spacecraft with very sensitive instruments which are often susceptible to electrical interference. Although the MIL-STD-1773 bus is a 1 Mbps bus like the MIL-STD-1553 bus, the fiber optics also provide a path to the much higher rate systems required in upcoming NASA missions.
