Paper Abstract

We experimentally demonstrate a resilient wavelength division multiplexed (WDM) fiber ladder network, based on optical add-drop multiplexers (OADMs), to interconnect sensors. It recovers operation after failures and it enables "selfdiagnosis", the identification of the failed element(s) from the patterns of surviving end-to-end connections at all operating wavelengths. A theory for such topologies, the "binary state connectivity analysis", used a matrix formalism to predict the surviving channels at the receiver node after damage occurs in one or more sites. We present experimental measurements for double failures in the network, demonstrating complete agreement with theoretical predictions.
