The Modular WDM-Gridconnect as a Passive Routing Structure with Distributed Interfacing Capabilities

Abstract

For communication services over transparent optical paths, specified in terms of bit rate and bit error probability, the maximum length is determined by detrimental physical effects like dispersion, crosstalk, noise or nonlinearities. Therefore, fiber-optic wide area networks employing wavelength division multiplexing (WDM) and optical bypassing have to be divided into several small transparent partitions. In this paper a scheme accounting for sufficiently short optical paths is introduced which is called Modular WDM-Gridconnect. In this approach the burden of interconnecting different network partitions (i.e., by using an overlay transport system as an interface) is spread over almost all nodes of the network. This property is referred to as distributed interfacing. The network can be extended step-by-step in a modular fashion adding no more than two nodes to the coverage area at a time. The advantageous properties of such an arrangement as compared to a straightforward partitioning are characterized by the cumulative transit traffic and the path lengths in a Modular WDM-Gridconnect cluster.
