Fault Diagnosis in the Linear Lightwave Network

摘要

This paper proposes an algorithm for fault localization in a Linear Lightwave Network (LLN). A LLN is an all-optical network using Linear Dividers Combiners (LDCs) as network nodes. These LDCs can perform either wavelength or waveband selective linear operations on optical signals including controllable power dividing and combining [1].rnIn general, the network environment is divided into a number of static disjoint subnetworks, as in Figure 1(a), each managed by an individual management process. A subnetwork might be connected to other subnetworks, and/or has inputs from Tx stations and outputs to Rx stations.
