Fibre optic networks in aerospace encompass the integrated assemblies of waveguide pathways, distribution nodes, and associated passive components that form complete optical data-bus architectures aboard aircraft and spacecraft, supporting high-bandwidth, EMI-immune communications across avionics, flight-control, and in-flight entertainment systems via topologies such as ARINC 664 (AFDX)-compliant optical backbones and MIL-STD-1773-based fibre-channel networks.
