FTTx describes, in practice, the architecture of fibre‑based
access networks used to deliver fixed electronic communications (
broadband internet, IP telephony and television) and is commonly referenced in telecoms contracts, wayleaves/servitudes, planning and regulatory documents. It is an industry description rather than a term generally defined in UK or Irish legislation or case law, though it is widely used in Ofcom/ComReg materials and commercial agreements.

(b) FTTB — Fibre to the building: fibre reaches the building, with the final in‑building segment over copper, coax or Ethernet/LAN. Performance and obligations may depend on landlord consent and internal cabling.
(c) FTTN/FTTC — Fibre to the node/cabinet: fibre terminates at a street cabinet or node (often up to several kilometres away), with the final connection over copper (e.g. VDSL) or coax (e.g. DOCSIS 3.1+).
Usage is consistent across England & Wales, Scotland, Northern Ireland and Ireland. Legal significance includes service level and speed commitments, network handover/demarcation, and property access rights (Electronic Communications Code wayleaves/easements in the UK; equivalent wayleaves and access...
