  • Very high-speed digital data bus
    Patent number: 4748617
    Abstract: A time-division multiplexed, data communications system allowing multiple user devices, including super computer buses configured in a local network, and other existing network hierarchies to exchange digital data over extended distances at speeds heretofore unattainable. The system includes a plurality of intelligent nodes, termed "DATApipe.TM. adapters", which are coupled to a fiber optic bus. The DATApipe adapters function as interface devices between the fiber optic bus and the I/O processors which are used to couple the user devices and networks to the DATApipe adapters.
