An optoelectronic router with a shuffle exchange network is presented and enhanced by adding micro-optical-electrical mechanical systems (MOEMS) in the network to add the ability to reconfigure the shuffle network. The MOEMS described here are fully connected any-to-any crossbar switches.The added reconfigurability gives the opportunity to adapt for different common application characteristics. Two representative application models are described, where the first has symmetric properties and the second has asymmetric properties. The router system is simulated with the specified applications and an analysis of the results is carried out. By using MOEMS in the optical network, and thus reconfigurability, over 50% increased throughput performance and decreased average packet delay is obtained for the given application. Network congestions are shown to be avoided throughout the system if reconfigurability is used.

“…In other words, the backplane fits very well together with the PCB communication system. The passive optical backplane is based on the fiber-foil technology [5] [6] [7], which recently has become commercially available. For scalability reasons, the passive optical backplane can optionally be extended with optical switching.…”

This paper presents a way of building modular systems with a powerful optical interconnection network. Each module, placed on a Printed Circuit Board (PCB), has a generic optical communication interface with a simple electronic router. Together with optical switching using micro-electromechanical system (MEMS) technology, packet switching over reconfigurable topologies is possible. The interconnection system gives the possibility to integrate electronics with optics without changing existing PCB technology. Great interest from industry is therefore expected and the cost advantages are several: reuse of module designs, module upgrades without changing the PCB, low-cost conventional PCB technology, etc. In the version described in this paper, the interconnection system has 48 bidirectional optical channels for intra-PCB communication on each board. For inter-PCB communication, a backplane with 192 bidirectional optical channels supports communication between twelve PCBs. With 2.5 Gbit/s per optical channel in each direction, the aggregated intra-PCB bit rate is 120 Gbit/s full duplex (on each PCB) while the aggregated inter-PCB bit rate is 480 Gbit/s full duplex. A case study shows the feasibility of the interconnection system in a parallel processing system for radar signal processing.

Fiber-optic interconnection networks for signal processing applications

Lecture Notes in Computer Science

1999

Abstract. In future parallel radar signal processing systems, with high bandwidth demands, new interconnection technologies are needed. The same reasoning can be made for other signal processing applications, e.g., those involving multimedia. Fiber-optic networks are a promising alternative and a lot of work have been done. In this paper, a number of fiber-optic interconnection architectures are reviewed, especially from a radar signal processing point-of-view. Two kinds of parallel algorithm mapping are discussed: (i) a chain of pipeline-stages mapped, more or less directly, one stage per computation node and (ii) SPMD (Same Program Multiple Data). Several network configurations, which are simplified due to the nature of the applications, are also proposed.
