Abstract

We present here a switch architecture that employs the inherent capability of optical fiber for storage. The switch is based on two rearrangably nonblocking stages interconnected by delay lines with different amounts of delay. Probability of loss as a function of link utilization and the size of the switch are investigated. In general, with proper setting of the number of delay lines, the switch can achieve arbitrarily low probability of loss. We have estimated that switches of 32×32 may easily be implemented with the ECL logic.
