The benefits of introducing optical networks in aircraft applications and an overview of related networking challenges are presented in this paper. Progress in the development of WDM-based Optical Backbone Networks (OBN) standards for aircraft networks is also reviewed. Optical networks can enable flexible, high bandwidth, low cost, and low weight communication links on aircraft platforms spanning military and commercial applications. This paper highlights networking challenges (architecture, systems and technology) associated with optical networks, and delineates opportunities for fiber optic systems in aircraft platforms through a case study comparing copper-based and fiber-based cable infrastructure. The paper also presents the status of standards development by the SAE International Avionics Systems Division (ASD) AS-3 WDM LAN working group.
