Development of a Scalable WDM LAN for Avionics Networking

The SAE AS-5659 subcommittee has undertaken the ambitious goal of drafting a standard for Aerospace WDM LANs. The backbone networks that this standard defines will transform the communications infrastructure in future platforms, providing a level of flexibility and scalability that is unattainable in existing architectures. In doing so, the organization of the vehicle will evolve from separate subsystems, communicating over closed interconnects, to an integrated, reconfigurable, upgradeable platform, where the cable infrastructure is installed once, and persists for the duration of the life-cycle.
