Optoelectronic implementation of the Register Insertion Bus high-speed network

The Register Insertion Bus (RIB) is a scalable optical network using a folded-bus topology. The access scheme relies on two buffers found in each station to hold packets that would conflict. An active fiber optic tap has been utilized for the switching of the packets that may conflict. In this paper we present an optoelectronic implementation using, instead of the two buffers, a fiber optic delay line memory loop. Passive taps are used for the control of the bus and the fiber loop. LiNbO/sub 3/ electrooptic switches are also used as active switching elements.<>
