FROM COPPER TO FIBER: THE EVOLUTION OF AVIONICS SYSTEMS IN AIRCRAFT THROUGH FIBER OPTIC INNOVATION

Abstract

In recent years, the complexity of modern aircraft and the need for reliable and fast data transmission systems have driven the aviation industry to seek advanced communications technologies. In this regard, fiber optics are particularly well suited to the stringent requirements of aviation due to their numerous advantages, including lighter weight, immunity to electromagnetic interference, high data throughput, and increased durability in harsh weather conditions. Fiber optic systems offer significant gains in data capacity, electromagnetic interference immunity, and weight reduction. These elements support vital functions including avionics, in-flight entertainment, and sophisticated monitoring systems, making aircraft operations safer and more efficient. A detailed comparison with conventional copper systems demonstrates how fiber optics may enhance airplane performance and save operational costs by lowering fuel consumption and prolonging system life. Although fiber optic systems offer many advantages, there are disadvantages and challenges that hinder their widespread use. High initial costs, complex maintenance, and the need for specialized training for installation and repair are some of the challenges. In addition, fiber optic components have durability issues due to aviation-specific environmental factors such as temperature extremes and vibrations. Based on the above, this paper reviews the development of aviation communication systems and the current state of fiber optic applications in these systems to examine the integration of fiber optic communication systems in aircraft, substantiating the advantages of fiber optics over traditional copper systems in terms of efficiency, performance, and reliability, laying the foundation for the idea of replacing copper systems to support nextgeneration aircraft avionics. The paper also highlights the importance and future opportunities of fiber optics in aviation and summarizes key ideas in this area.
