Starlink v2: Laser Link Architecture
The Vacuum-Speed Global Backbone
The Optical Breakthrough
The transition to Optical Inter-Satellite Links (OISL) marks the most significant shift in satellite networking history. By using lasers (infrared spectrum) instead of radio waves for backhaul, Starlink v2 satellites can achieve throughput exceeding 100 Gbps per link.

Vacuum Propagation vs Fiber Refraction
The High-Frequency Trading (HFT) Alpha: Shaving 10ms off a NYC-London route is worth millions in the financial world. Starlink's laser mesh achieves this by moving data through the vacuum of space rather than standard fiber-optic glass.
Mesh Topology in Motion
Unlike terrestrial routers fixed in data center racks, Starlink v2 nodes are moving at 7.5 km/s. The "Space Mesh" must maintain quadruple laser links (front, back, left, right) while constantly calculating the shifting geometry of neighboring planes.
Bypassing "Geopolitics of Fiber"
OISL allows a packet to traverse from a ship in the middle of the Pacific directly to a terminal in London without ever touching a ground station in a third-party country. This provides unprecedented data sovereignty and resilience against subsea cable cuts or ground-segment congestion.
Future Scalability
As the constellation grows to 30,000+ nodes, the orbital mesh will transition from a simple ring topology to a dense fabric. This will enable high-availability pathways that can dynamically route around "congested" orbital planes during peak usage.
