FTTH (fiber to the home): shared consumer fiber. High but non-guaranteed speeds (shared at the aggregation point), frequent asymmetry, and above all no repair SLA: an outage can last days. Price: €40–90/month.
FTTO (fiber to the office): an end-to-end dedicated fiber, contractually guaranteed symmetric bandwidth, carrier monitoring and a 4h repair SLA. Price: €350–700/month depending on speed and area.
The pragmatic doctrine: FTTO on the site whose downtime is expensive (HQ, production); FTTH + 4G/5G backup on secondary sites — that combination often delivers better real availability than a single FTTO, for half the price. And if the site hosts exposed servers, the real question becomes: shouldn’t they be in a data center?
