<p>A multi-star fiber optic network achieves improved access periods by grouping terminal devices into subnet-i works that are connected to a bus, with token passing or collision detection being localized to individual subnetworks, and with communication between subnetworks being conducted over the bus via non-interfering optical channels which may be light sources having different wavelengths or different channel frequencies. Each subnetwork includes an N-to-1 star which receives optical signals from terminal devices in the subnetwork and 1-to N star which distributes optical signals to terminal devices in the subnetwork are a transmit repeater, a receive repeater, and a buffer memory within the receive repeater of each subnetwork.</p> |
