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. The distribution circuit is coupled to an input/output port of the data storage system but is not connected to the host computer or directly to the computer workstations. Optical signals provided by the distribution circuit are carried by a plurality of optical fibers wherein each pair form a bidirectional data link to a specified workstation. An interface card is disposed in each workstation and is coupled to its backplane. The interface card is adapted to transform optical signals into electrical signals and vice versa for display or for transmission to the data storage system.
