In this paper, we study the benefits of using multiple fibers per link in optical packet‐switched networks. The node architecture is presented and various contention resolution schemes are evaluated. Comparisons are made between the multifiber switch with a small number of wavelengths per fiber and the traditional single‐fiber switch with a large number of wavelengths per fiber. The analytical and simulation results show that although the multifiber switch cannot easily perform as well as a switch with full wavelength conversion, compared to the traditional switch, it significantly reduces the number of wavelength converters and fiber delay lines while achieving a lower packet‐loss rate. © 2004 Wiley Periodicals, Inc.
