Abstract: A fiber optic data distribution system for distributing image data between a data storage system and a plurality of image workstations using embedded control signals and a fiber optic link. The data storage system, a host computer, and a plurality of image workstations are all coupled together by way of a local area network. The host computer includes network software and associated files that provide control information and functions for the distribution system. The host computer controls access to the distribution system by setting up the data storage system and workstations and initiating data transfer to and from the workstations. The data distribution system includes a distribution circuit that comprises a high-speed logical switch that is capable of data transfer rates on the order of 100 megabits per second. The distribution circuit is also an electrical to optical converter which transforms electrical signals stored in the data storage system into optical signals and vice versa.

Abstract: High speed transfer of data over any distance can be easily achieved using high speed optical fibers and an optical fiber interface that couples signals transferred using the optical fibers to and from a computer. A specific implementation of the present invention is a fiber optic interface for a Macintosh brand computer that provides a direct fiber optic interface having no parts external to the computer that couples data to and from an optical image storage unit. The fiber optic interface circuit comprises an optical receiver coupled to a fiber optic cable for receiving optical signals from the image storage unit that converts them into corresponding electrical signals. An optical transmitter is coupled to a second fiber optic cable for converting electrical signals derived from the computer into optical signals and for transmitting them to the image storage unit.
