 Although ARINC 818 was developed specifically for avionics applications, the protocol is already being used in sensor fusion applications where multiple sensor outputs are multiplexed onto a single high-speed link.Features added in ARINC 818-2 facilitate using ARINC 818 as a sensor interface.The ARINC 818 specification does not mandate which physical layer is to be used and implementations are done using both copper and fiber.
