Tier planning
A hub is upgraded as demand grows (C → B → A), gaining cable bays, throughput and — at Type A — its own SF6 root plant. A hub is never downgraded: committed capacity stays.
- Type C — 1 link · 3.8 GW · connects only to a Type A
- Type B — up to 3 links · 11.4 GW · connects to A and B
- Type A — up to 5 links · ~20 GW · root, SF6 plant
Type A — the topological root. Hubs are never downgraded.
