Abstract

An N×M lightpath concentrator is an optical component for concentrating lightpaths from N incoming fibers to M outgoing fibers where N>M. In this paper, we propose a novel design of lightpath concentrators that gives significantly better performance-complexity tradeoff than the existing design. The proposed design uses 2×2 switch elements to form rings which connect the inputs to the outputs. The incoming lightpaths are circulated along these rings in order to reach the available outputs. We demonstrate that: i) the proposed design gives significantly smaller blocking probability than the existing design when both designs have about the same complexity, and ii) the proposed design has significantly smaller complexity than the existing design when both designs have about the same blocking probability.
