Optical Inter-Satellite Links: The Future of Space-Based Networks
Introduction Satellite communications are entering a new technological era. For decades, satellites primarily depended on ground stations to receive, process and relay information. A satellite would receive a signal, send it to a ground gateway, and the data would then travel through terrestrial infrastructure. That architecture is changing. In 2026, optical inter-satellite links (OISLs) are becoming an increasingly important technology for next-generation satellite networks. Instead of relying entirely on ground
