Abstract : In this report, a platform design for packet-switching optical time division multiplexed (OTDM) networks operating at ultrafast bit-rates is presented. The design is implemented in a prototype 8-node transparent shuffle network. The flow control in this network is based on a self-routing scheme developed to reduce the address processing delay at each node and make the network scalable. Deflection routing is used as the contention resolution principle. Several issues on designing optical networks, such as the node configurations and finding the optimal routing algorithm for maximum throughput, are discussed. Subsystem experiments demonstrate the functionality of the components including a 100 Gbps optical packet compressor and a parallel array of Terahertz Optical Asymmetric Demultiplexers (TOADs) used for header address recognition. Precision delay lines are used for synchronization and timing, based on optical self-clocking techniques. The overall capability of the ultrafast packet-switching testbed is evaluated.
