Fiber-optic interconnection networks for signal processing applications

Abstract

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.

A Comprehensive Analysis of Four Channel CWDM Network System

“…It can also be used in fiber-to-the-x (FTTX) broadband networks, where it allows multiple homes or businesses to share the same fiber connection. The use of optical CWDM fiber can significantly reduce the amount of fiber required, making it a cost-effective solution for many applications [2].…”

Efficient many-to-many real-time communication using an intelligent Ethernet switch

“…Modern and future parallel processing applications, such as radar signal processing applications, often involve many-to-many communication [1] [2]. Much work has been done on many-to-many communication [3][4][5][6][7][8], but has thus far primarily been on the software level with algorithm solutions for scheduling, routing, scalability, security etc.…”

“…Much work has been done on many-to-many communication [3][4][5][6][7][8], but has thus far primarily been on the software level with algorithm solutions for scheduling, routing, scalability, security etc. Work on the network level was proposed in [1] [9] [10], but is developed for other types of networks and differ significantly from our strategies of the many-tomany communication for switched Ethernet networks. A reliable many-to-many multicast protocol for group communication was described in [10], but aimed for widearea ATM networks.…”
