Abstract
A fiber-optic network has a branching net in which only three optical waveguides are interconnected at each of a plurality of active or passive branch points (A, B). The branch points are designed to permit bidirectional transmission in each of three paths. Subscriber facilities (F) are connected or connectable to the optical waveguides of the network at arbitrary points. To increase reliability, a fiber-optic ring main (50) is provided to which the ends of the optical waveguides forming a branching net are connectable via controllable optical switches (D).
