Relation of OSNR and PLR for nonintrusive fault detection in all-optical IP-Ethernet-WDM networks

Abstract

I present an analytical expression for the relation of the packet loss rate (PLR) with respect to the channel optical signal-to-noise ratio measured nonintrusively in an all-optical, wavelength-routed network. This closed-form expression is aimed for rapid, nonintrusive fault detection of lambda services. This relation will help achieve reliable all-optical networks with no extra optoelectrical cost due to monitoring, and yet have digital parameters such as the PLR in the service level agreements. Analytical results considering performance thresholds for triple-play services, gigabit Ethernet framing, and forward error correction are discussed.
