How it works
Higher spectrum on copper attenuates quickly—success requires typically <350 m from the distribution point, often lower in practice. Self-install modems negotiate profiles like 330/50 Mbps marketing tiers when physics allows; otherwise sync falls sharply.
Deployment footprints
Street cabinets with “fibre pod” sidecars served early adopters; MDUs sometimes used basement DPUs. Where FTTP overbuild arrived later, G.fast may be frozen for new orders, nudging upgrades to full fibre instead.
G.fast versus FTTC and FTTP
FTTC VDSL2 tops near 80 Mbps down on ideal shorts; G.fast stretches that on shorter loops. Neither matches FTTP’s symmetric potential or weather resilience. If both G.fast and FTTP quotes appear, fibre generally wins on longevity.
SwitcherMate clarity
We emphasise address-level certainty so you are not sold a G.fast badge when your loop length never qualified—common source of buyer’s remorse.
Why FTTP eventually wins
G.fast was a sensible interim while ducts filled with blown fibre slowly; operational cost and uniformity now favour end-to-end optics. If you are offered G.fast today alongside FTTP for similar monthly cost, lean FTTP for longevity—unless install logistics make G.fast the only quick fix before an office deadline.
Document sync profiles after installs if you later dispute performance.
