Applications

14.4.1 LEO Mesh Backbones — Knitting LEO satellites together with optical inter-satellite links to create a sovereign space-based data highway that bypasses terrestrial chokepoints entirely.
14.4.2 LEO-GEO Optical Crosslinks — High-throughput free-space optical links connecting LEO constellations to GEO relay nodes, enabling persistent, high-bandwidth data delivery without crowded RF spectrum.
14.4.3 Optical Ground Stations — Sovereign telescope-based ground terminals that receive laser downlinks from satellites at multi-gigabit rates, replacing or augmenting RF ground stations for high-throughput data delivery.
14.4.4 Quantum-Compatible Optical Links — Satellite optical inter-links engineered to carry quantum key distribution alongside classical high-rate data, enabling cryptographic keys that no eavesdropper can copy without detection.
14.4.5 Free-Space Optical Standards — Developing and implementing interoperability standards for free-space optical links so that sovereign constellations can talk to any compatible terminal without vendor lock-in.
