AMCA will be the world‘s first fighter Aircraft and to have a Fly-by-Optics system, although is not a very complex tech or ises some high level tech, it just replaces wires with optical fibres which helps the aircraft in being resistant to EMP and is a lightweight system. Idk why others don’t use this tech.
Fly-by-optics is sometimes used instead of fly-by-wire because it offers a higher data transfer rate, immunity to electromagnetic interference and lighter weight. In most cases, the cables are just changed from electrical to
optical fiber cables. Sometimes it is referred to as "fly-by-light" due to its use of fiber optics. The data generated by the software and interpreted by the controller remain the same.[

Kawasaki P-1 is the first production aircraft in the world to be equipped with such a flight control system.
