A fiber optic data interchange network comprising a plurality of nodes, or drops 10a, 10b, 10c . . . , interconnected by fiber optic cable 12 (FIG. 1 ). Encoded data signals originating at any node are circulated around the network, allowing multipoint (or multidrop) data interchange. Each node includes a data encoder, transmitter, fiber optic receiver, data decoder, clock recovery circuit, and a repeater, i.e., a combination of the fiber optic receiver, an invertor (providing pulse width distortion correction) and the fiber optic transmitter. Thus each node is capable of originating data transmissions and receiving/relaying transmissions from a preceding node.
